    Depends on the kind of studio. TV studios, sure, but they actually wanted the HD overall -- it was largely seen as a way to increase viewership.

    Most production studios were already shooting on film, and editing digitally, so adding HD to that toolchain only meant that you could shoot for more than 10 minutes continuously, and didn't have to get the film processed. Adding 3D is a new camera, probably a new lens (depending on the camera), and some changes to the existing editing. And of course, some studios still use film, others waited for video to catch up to film before they bought into the digital thing (eg, cameras with 35mm size sensors that can use traditional lenses, etc).

    Like HD, too, it's not as if there's going to be an overnight jump to 3D. It might fail this time.

    RealD-style polarizing (eg, circular polarizers) is just as effective as shutter glasses, and adaptable to some TV technologies (DLP, in particular). But you'll need a new TV.

    The only reasonable add-on to existing hardware are LCD shutter glasses. They're nowhere near as cumbersome as they were back in the 80s, but yeah, still extra heavy compared to passive glasses, and you need the battery, too.

    "Prismatic screens similar to 3D photos" is called lenticular 3D/stereoscopy. It's flawed for the same reason the old horizontal/vertical polarization was... it fails unless you're sitting perfectly straight. That's already pretty much failed in the theater, and is a no-go entirely for the home, I suspect.

    The other modern glasses-based technology is Dolby's 3D system, which they call "wavelength multiplex visualization". Basically, they mess with the colors for left vs. right eye, but in very tiny bands, so you don't see any color shifts. Otherwise, it's the same idea as polarization: filter at the projector, filter at the eye.

Adobe would drop a nice, snappy Flash player on them tomorrow if Apple wanted to support Flash.

    As for complaints about Flash dragging down a desktop, the only thing in a typical flash stream that can do that is a full HD AVC video running unaccelerated on a desktop PC. That's a non-issue for handhelds. They don't need to play back full HD... most are 480p or lower in resolution. And every major high-end smart phone has hardware acceleration for AVC playback.

I love tabbed browsing, use it on my mobile and desktop (no frickin' idea how iPhone users get along without it and still manage to suck up for much bandwidth... oh, I guess that's the constant reloading of pages as you switch to look at something else or run a different app), but you don't want the tabs in your face on the mobile device.. they take up too much space. Dolphin on Android (at least the old version) does this right, you swipe to move between pages, and you can pop up the tabs if you want to get at them.

    PC-based tablets have been out for nearly a decade in some forms, but like other super-small PCs, they were sold at a premium for quite some time. The advent of cheaper tiny notebooks, thanks to the popularity of the netbook, is one factor... many of the new tablets are based on Netbook-class x86 processors. There were a bunch of new ones at CES, but you can buy these today.. they're not copying Apple.

    Then you have the others. Companies like Archos and Viliv have been making tablet-sized PMPs... dedicated media players with 5-10" screens, for many years now. They have been moving this form factor to run Windows on the high end, Android on the low end, rather than just some dedicated PMP OS. There are a bunch new ones at CES, but you can buy these today, they're not copying Apple.

    Then there's the phone folks and technologies... the ARM processors used for phone (and some of the aforementioned PMPs) have recently become powerful enough for non-phone things. Between the Android OS and the 1GHz ARMs, these can actually take on the jobs that the netbooks do. Nokia actually started making this kind of device several years ago, the idea being easy, portable web browsing. This year, there are dozens of them.

    The basic idea is that, like your PDA/Smart Phone, there are any number of PC-class applications that work well outside of Windows and/or a traditional PC. Rather than build a device to read books, a device to play media, a device to surf the net, etc. you build one general purpose application processor that do all of these things, plus new ones that come along. Android OS is one of the big movers here (and it's only been out for just over a year)... one free, consumer friendly OS that consumers actually use and OEMs don't have to pay big to license. Perhaps some other stuff built on Linux will catch on here too, such as MOBI or Google's ChromeOS.

    But it's already a problem pretty much solved, and Apple's really just doing the same pretty obvious thing at the same time.

If PA Semi took an ARM Architecture license, they could have done like Qualcomm and tweaked up the A8 to higher performance. I have heard all the rumors going around, but nothing confirmed.

Maybe a MALI 400 or one of the higher-end PowerVR cores (like the one Intel uses in their low-end PC chipsets... weak for a PC, but still an upgrade from the iPhone). None of these are Nintendo class, though.

    What we do know: the iPad battery is 25Whr. If they're claiming "up to 10 hours" of life, then one must assume the minimum power draw for useful work is 2.5W.. otherwise they'd be claiming more. The CPU is only a small bit of that power consumption.

    The Tegra2 pulls an average 500mW running its two dual 1GHz ARM Cortex A9s, on a 40nm SOC. Considerably less power just playing back full 1080p high def video, somewhere around 200mW. Current tablet/phone chipsets can draw over a watt playing back high-def video, because there so much more CPU involvement.. that kind of tracks Apple's numbers here for battery life. The nVidia releases all say things like "12+ hours of HD video playback", but obviously, this depends on the whole system... the LCD display can use much more power, if you're not careful. The demo unit nVidia was showing off claimed 16 hours of HD playback, 140 hours of music playback, on a single charge. At least some of the various companies showing off Tegra 2 tablet computers at CES were making similar claims, but I don't know for certain if MSI was one of them.

    So yeah, it's very, very believable that the MSI unit, or any Tegra2 based tablet, will dramatically outlast the iPad doing the same kind of things. It's also quite possible that some will not. If you push it (it's fast enough to run the Unreal 3 engine at the typical 1280x768 resolutions you find on tablet computers), it's going to eat power much faster than just reading a book or playing a movie. This GPU is similar to the GeForce 6000 series, the claim is that it's 2x-3x as fast as the unit in the orginal Tegra chipset.

    I'll be shocked if Apple's annual iPhone upgrade doesn't include at least one model running the A4 CPU, perhaps at a slightly lower clock speed. NVidia is also working to put the Tegra 2 into this years smart phones. Pretty cool stuff.
