Sex, liquor and gambling are not Las Vegas' only tempting vices -- there are electronics, too. The 2004 Consumer Electronics Show is in full swing. Below is a informal report from the show floor: I've been walking around the place ogling flat screens of all varieties (plus one close-to-flat screen, details below) and seeking the elusive perfect portable music player I'm after. Read on to learn about some of the interesting products being hawked, and about some things for which you'll have to wait.

Even for convention-happy Vegas, CES is one of the city's biggest annual events -- approximately 120,000 attendees and more than 2,000 vendors have gathered to sell, buy or window-shop all sorts of electronic and related products, from high-end turntables (for pre-digital music stored on extruded polyvinyl) to message-scrolling LED badges, batteries and chargers, metal detectors, digital cameras, strange-looking MP3 jukeboxes, LED-strewn computer cases, and more.

Repeat: CES is not necessarily about computers -- at least it's not centered around devices with keyboards, rectangular CPUs and monitors. There's plenty of computer industry action here -- Michael Dell is one of the keynote speakers, for instance, and several of the biggest exhibitors are computer manufacturers -- but the "consumer" part of Consumer Electronics Show is an unsubtle hint that anything which beeps, glows, plays recorded music, takes batteries, or has a circuit board buried somewhere within is fair game. (I'll skip details on some of the products that slip past even this catch-all description, among them ceramic figurines and other gimcracks.) There are companies represented who will cast your industrial design in aluminum, and one which will let you do the shaping yourself, but in plastic. There's no way to see everything here; here are some impressions of what I did see, though.

May I interest you in a humongous television?

Plasma and LCD displays are everywhere at CES, in the form of new but current products, prototypes to whet your appetite for next year, and as visual aids selling other products. The ongoing switch in the U.S. to digital broadcasting and the uncertainty attached to early adopter purchases generally make me glad not to be in desperate need of a television right now, but the home-entertainment hardware on display is enough to make my eyes water. LG, both inside the show and on a billboard outside the convetion, proclaims that they have the world's first 76" plasma television (their booth has this on display, and many smaller ones as well), while Samsung's giant blue-themed booth tops that by featuring a crowd-paralyzing 80" model; people stood to watch the demo loop, which was mostly natural imagery rather than the bikini show running on many other companies' sets.

(This display, and LG's 76" model, brings up a point that seems to generalize well to many of the claims made at CES and in less overt marketing circumstances as well: Samsung calls theirs the world's first 80" plasma TV, but they also are showing a 70" model inexplicably labeled "The World's First Plasma TV." These companies are far from the only ones making dubious contradictory claims; the standard of evidence to be a "world's first" at CES seems lower than you might expect.)

TV and monitor overload is easy: Toshiba, Panasonic, Sony, Philips, Sony, Aquos (made by Sharp), Daewoo, Apex, ViewSonic, and other brands more or less familiar to electronics-friendly American householders all had their LCD displays out, both computer-only and TV-friendly devices. So did low-end, badge-stamping names like LennoxSound and Coby; some of the Coby displays had lifelike paper screen mockups rather than actual moving images. (If you're in the market for a flat-screen television, beware that some LCD televisions are really only monitors; if you need a tuner, don't assume one is built it.)

LCD computer monitors are now so mainstream that nothing stands out as spectacular in what I saw of this year's crop, though it's nice to see that bigger models are eroding 20" as a gigantic-LCD standard and pushing it down to merely large: suffice it to say, 20" LCDs may remain in the high end of computer displays for a little while, but far larger ones are now at the high end.

While on the topic of big-screen displays, two products from InFocus stand out: First is their 7"-thick, 61" screen (the model is labeled Screenplay RPTV; this may change before it ships), which is easy to confuse with a plasma model, but it's not -- it's actually a rear-projection system that's had its guts folded into a silvery rectangle taking up about a foot of vertical space beneath the display's screen. This rearrangement means it lacks the spare, picture-frame look of most plasma TVs, but the result still whips old-style console sets. Pricing is not yet set (it's not shipping until later this year), and smiling InFocus representatives deflected the question of price from several people, including me, only hinting that it would be cheaper than similarly-sized plasma models. And only your aesthetics and stud placement can determine whether a near-100-pound television qualifies as "hangable" for you. A 70" version is set to follow.

The second product, happily, does have a price; unhappily, that price is $2700. That much money buys you their LP120 model, introduced earlier this year, which InFocus says is the smallest XGA projector on the market -- it's about the size of a 5-pound block of cheddar cheese, weighs less (a hair less than two pounds) and has to be seen to be believed. It sits strictly in the middle end of the brightness scale (1000 lumens) but on the moderately lit convention floor, the image is actually hard to distinguish from that of a non-projected screen. I'm not sure at what price I would buy this (I would really like to take a projector this size along with me, everywhere), but at almost three grand (and replacement bulbs are the industry-norm 2000/hour life, $300-400 replacement cost) this is for business travelers and jillionaires more than those of us who'd like to watch "L.A. Confidential" in a hotel room.

Black boxes for your humongous television.

The electronics industry would obviously like you to buy a big (expensive) display of some sort, and they're happy to help supply moving images to make it worthwhile. "Convergence boxes," with different logos on the front, but with for the most part similar capabilities and interfaces, are on display from many manufacturers. Convergence is like perfection, though -- the pursuit is worthy, but ongoing. There will always be new file formats, media, and output devices to fold in.

Drawing a composite sketch, this year's standard-issue convergence box runs embedded Linux like TiVo (for instance Daewoo's DX C811N Digital Video Recorder) and in many cases the TiVo name (under license), holds a hard drive from 80-120GB (like Toshiba and Panasonic are offering), features composite and S-Video outputs (nearly every maker), lets you record to DVD-RAM or DVD-RW/+RW, and is still at standard resolution (rather than High Definition). High Definition PVRs will eventually arrive in force; I bet they'll be next year's big trend of the show. Also next year, you'll probably see more all-in-one boxes which can play back WMV files; one Microsoft display area was showing off the first WMV-capable DVD player, the Malata DiVA DVR-489. Confusingly enough, a few feet away Microsoft was giving out sample DVDs with WMV format high-density program examples; these can't be played back (for now) in anything but a PC running Windows; the Malata and similar, soon-to-market players are for standard definition only.

(The Daewoo PVR I mentioned, by the way, is really a different beast altogether, built for things like monitoring multiple security cameras: I lust for the built-in 8-way video multiplexer).

Considering that PVRs are becoming ever more commoditized, I hope that Apex's prototype PVR-9280 (with a DVD burner as well as an internal hard drive) becomes a reality. When I asked about that, Sal Fiore from Apex did what a lot of exhibitors at CES have to do: he hedged, resorting to a smile and calling it "a definite possibility." Though known as at best a medium-grade electronics brand, Apex has followed the path of eMachines by making more impressive products over the last few years. I'd be happy to find the PVR equivalent to today's low-end DVD players.

On the high end, though, Samsung was showing a working and very polished looking Blu-Ray recorder, which they say will be able to store up to two hours of high density programming (and 12 hours of standard) per Blu-Ray disk. (Blu-Ray, mentioned briefly here, is an optical format storing up to 27GB on a CD-sized disk.)

And now for something completely obscure ...

Since I'm in the market for a portable Ogg Vorbis player, I've asked at several of the manufacturer's booths whether they plan to support it, and specifically whether they will sell CD-based units with Vorbis decoders. (I've been encoding my CDs to Vorbis for the last few years; YMMV, but I like it.)

The results are about what I'd expect: a polite "not on our radar screen" is the gist of responses from representatives at Creative, Sony, and nearly all the other Big Names; at the lower-end makers booths (who, after all, make things like $40 MP3 CD players available at mass-market retailers), I never even found anyone who'd heard of Ogg. iRiver is the current standout in this regard, since they're releasing firmware to make their CD-based players Ogg-friendly; I'll be visiting iRiver's product lounge soon to take a look at their current lineup. I also found flash-based players from Samsung and Rio.

This isn't surprising in the crowded world of audio codecs: MP3 has the benefit of years of market saturation; Microsoft has the research and marketing clout to develop and license WMA; and the Apple touch, via ITMS, has make AAC a nearly overnight contender. (Microsoft was showing off in a dedicated booth a few dozen models of portable audio players, like the Rio Nitrus, that will play WMA files in addition to MP3s, including the smallest 20GB hard-drive based model I've yet encountered, the not-yet-in-the-U.S. Toshiba Gigabeat MEG200J. Think of portable audio as sculpted by Minox.)

However, I did find one working CD-based Ogg-playing portable (model MCD-CM600, part of the "Yepp" line) on display in the Samsung area. "On display" is pushing things; several examples of the player were on hand, but behind plexiglas as window dressing rather than as a demonstration product. A company representative did some Won-to-dollars calculation, and said the player is available in Korea for between $130-140 dollars at current exchange rates, but that Samsung had no current plans to sell it in the U.S.

Tomorrow, look for a report collecting some of the wackier (and stupider) stuff at the show -- like a Segway do-alike (sans balancing brains and with more wheels), the electronic home of the future as seen from 1982, interesting swag, and the sad fate of the Wurlitzer name.

A random reader writes: "In an article at PCMag.com, Bill Machrone describes what has to be the coolest printer ever (or close to it). A company called Versalaser sells a printer which uses a laser and can cut/write on everything from paper to wood to stone. Available in 25-50 Watt models, starting at only US$10,000. Great for the geek who must have it all! Unfortunately, Windows drivers only at this time." We mentioned this wondertool before.

bwags writes "I ran across this VersaLaser desktop Laser Cutting and Engraving printer. I really do not know what I want to do with it, but you gotta admit it is cool. Maybe make some balsa wood airplanes. At only $10K, I want the purple one!"
