Sharp Zaurus SL-5600 PDA Review
An anonymous reader sent us a link to a review of the Sharp Zaurus SL-5600 PDA. This Linux based handheld with a built in qwerty keyboard with decent connectivity. As with most PDAs, there are a lot of tradeoffs that
have to be made yet. Read the review to see what they are.
Looks like their web server is running off their PDA. *ba-da dum*

Shoot -- I'm not an early adopter and I've had mine for over a year. This is not news.
On the other hand, the C700, 750, and 760's are hot, and I want one!

A long time ago, when I first heard about Sharp releasing the Linux based Zaurus 5500 PDA, my interest was peaked. I was just dying to see what it could do. Alas, I never had a chance to try one out for myself. Over the next few months I plan on purchasing a new PDA to take over from my Palm IIIc, and just recently, Sharp was good enough to send us one of the newly upgraded Zaurus SL-5600 units and I was able to finally give it a whirl. Let's see how things shaped up.
Inside the Zaurus SL-5600 Box
Meet the Zaurus SL-5600:
Included in the box is what you'd expect for any new PDA including cradle, power cord, instruction booklet, and of course your standard Windows software CD-ROM.
At first glance, I was surprised at the size of the PDA Unit, measuring 13.8cm x 7.4cm (5.4" x 2.9") and a thickness varying from 1.8cm to 2.3cm (0.7" to 0.9"). It also weighs in at a hefty 203g (7.1 oz). This is pretty big for a new PDA, and it's even bigger than my old Palm IIIc. With size comes issues like how to carry it (pocket, bag, briefcase, etc.), but size can also mean more features. Lets leave the size issue for later, and take a better look at the unit itself.
The Zaurus SL-5600 is a very large PDA.
Right from the start I liked the appearance of the Zaurus. The plastic silver casing is attractive to look at, but its resistance to scratching would worry me. It doesn't look like it could take much of a beating from use. The big 3.5" reflective TFT screen (320 x 240 resolution, 65,536 colors) is sharp and clear. It displays well in various lighting situations, something I can't say about my Palm IIIc. Also included is a clear protective cover for the screen - a nice feature. The colours are bright and vibrant, and contrast very well. Below the screen are indicator lights for E-mail and Battery indicator lights, a very useful addition in my opinion.

At this point, there is a break in the casing, and my favourite feature of the Zaurus comes into light. Sliding down the bottom section of the case reveals the QWERTY keyboard. The trend for most new PDAs is to move away from the stylus based text-input to a finger-keyboard type input method, a move I totally agree on. The keyboard on the Zaurus is quite responsive, and it has a pretty good layout. One of my only gripes is a lack of an 'Esc' key, as I struggled to use a port of Vim which I installed on the unit. A stylus is still a good idea for navigating menus and selections, and a software based graffiti-like text input method is also available. A neat feature of the software-based keyboard is the option to customize it to recognize your own personal handwriting. This could allow you to write more naturally, than say, writing using Graffiti on a Palm device. I definitely found that I could input text faster using the Zaurus's keyboard using my thumbs than with a stylus.

Under the keyboard is the usual set of easy access keys, included with almost every PDA. These include Calendar, Address Book, Home, Menu, and E-mail. Keys for Cancel/OK are also included on either side of the "cursor key", a navigation button that allows you to scroll your cursor up/down, left/right in any of the applications. This is a nice addition, and I found it quite handy.
Features:
The Zaurus SL-5600 contains an Intel XScale processor at a speed of 400Mhz. I found this processor very powerful, and the Zaurus was very responsive. Applications launched quickly, and I was easily able to p
In the end $499.99 quickly builds up to about $599.99.

The 5600 is native Linux -- it uses an embedix distro w/ Qtopia for the front end. There's also an Open Source distribution, which frankly, I prefer.

Funny, just before seeing this posted, I had just finished reading a review of the 5600 at geek.com . Since the review posted is slashdotted, maybe you can check that one out.
My beliefs do not require that you agree with them.
It's not really a PDA, it's a pocketable Linux computer.
First, the PDA side of things. People criticise it for having weak PDA features which, compared to Palms, and that's somewhat true; my previous Psion PDAs had a few extra features around the edges that I miss, but by and large the PIM features are fine for my moderately advanced use.
But there's so much more! SCUMMVM in the palm of your hand with mp3-encoded talkie versions of Fate of Atlantis or Day of the Tentacle is pretty nifty.Add a Wifi card, install Wellenwreiter or Kismet, and go low-profile warwalking. I have a Pocketop IR folding keyboard for long documentation on the go; the screen rotation software Just Works, unlike a lot of PocketPCs.
Unlike Palm owners, I can handle DOC and XLS files native on the device; this is particularly key because the Zaurus is a computer in its own right and not a PDA. The Hancom office apps shipped with it are usable enough for quick on-the-go editing and creation. I could do with one of these now for instant printing of invoices when I'm out at a client's site.
The big compelling piece of software is OpenZaurus, a completely open source and regularly updated distro to replace the Sharp ROM. It's a bit like trading Debian stable for unstable; kinda hacky at times, kinda buggy at others, but it's so exciting to get a massive batch of upgrades every few weeks full of improvements. It's never been buggy enough to lose my PDA data, and in any event with multisync, unison and rsync my data is backed up six ways to Sunday.
Other people like apps like opie-reader for ebooks, portable Ogg players (there are a few), portable DivX playback, email (this is noticeable ropy under OpenZaurus, but getting better), and many more... For more ideas, see this thread on zaurus.com.
Downsides? I find the QWERTY keyboard wearing after a few minutes, hence I have the Pocketop, and I've managed to scratch the screen under the handwriting recognition area so I can't really use it any more (I think that was my fault, to be fair). The battery life sucks too, but then it does on all these colour mobile devices. Apparently, the SL5600 is better.
So basically, if you want a PDA, get a Palm. If you want a pocketable Linux computer in a PDA form factor with respectable PIM features and a mountain of open source apps, get a Zaurus.
You win again, gravity!

480x640 is a special screen resolution for the dyslyxic. Everything is displayed as though it was rotated 90 degrees. Since dyslexics can tell top from bottom easier than left from right, it makes it easier for them to read lines of text that go from the top to the bottom. There is still the problem where they have problems deciding which line to go to next, but the new PDAs with this resolution will have arrows on the bottom to help them choose.
The 5600 is a great PDA, I really like mine. As far as syncing with Linux though, forget it. The CD comes with software to sync with Outlook, that's it. Apparently the Qtopia-Desktop software for Linux allows you to backup data, no syncing though. I say apparently because I cannot get it to run on my Redhat 9 system. From what people are saying in the Sharp forums, not too many people have had success with it. Also, with the 5600 and the latest ROM update to the 5500 the PIM data format is different so if you were syncing your PIM data in Linux you won't be able to any more. The people who were working on syncing software have had to start over. It appears Sharp is leaving Linux desktop support for the Zaurus up to the community, and they are not being all that cooperative. The Kompany apparently has syncing on their list of features to add to their tkc PIM apps for the Zaurus. Of course they are only worried about making sure it syncs with their product Aethera. Its really too bad, I'm sure if Sharp would just cooperate enough to create some sort of libraries or tools for getting the Zaurus data to and from the desktop people would be writing sync software for every PIM desktop app under the sun.
I bought the 5500 when HSN was clearing them out a few months ago... but I ended up returning it. While I really loved being able to hold linux in my hand, I quickly realized that it just wasn't a replacement for my Palm Vx.
:)
The most limiting factor was battery life... which the 5600 claims to improve. Any linux geek who will play with one of these things will be playing HARD... ogg decoding, game playing, etc. These things burn up battery life, and you quickly need to make a run for the nearest AC plug.
The other thing that discouraged me was filesystem management. Installing packages wasn't smooth and required some fancy footwork to install them on CF/MMC cards. And if you drain your battery and don't recharge within 24 hours (perhaps less), you'll lose anything not in flash ROM or on a memory card. Sure it's the same with any other PDA... but my palm can go for weeks w/o a charge... and I can recharge it with a 9v battery if I'm desperate.
There are hacks to setup backups to a CF card or whatever, and hacks for wireless connectivity, and hacks for getting X apps to run, and hacks... and hacks... but you start to realize that the entire thing is about hacks... it's not clean. It made me miss my Newton. Flexibility? No... but sure was slick!
Two things would have made me keep it:
1. Better battery life (fixed in 5600?)
2. Ability to boot off the CF card and turn the device into a full-speed, fully functioning palm emulator (the ones I tried had serious limitations). A dual-boot pda!
Just my $.02 - I look forward to trying again in a couple of years

In fact, since the system is based on Free Software, they should just release the whole source code to their PIM apps and be done with it. A programmer would jump up from the "community" to take care of their Linux synchronization needs- and probably someone else would volunteer to improve the UI on the PIM itself (which needs a lot of work in comparison to the competition from Palm)
By selling a Linux PDA, but not distributing the code to most of the applications, Sharp is getting the worst of both worlds in terms of user acceptance.
Some more technical detail:
Why does pseudo-XML waste space?
Because more than 50% of the total file is repetitive boilerplate. The addressbook.xml looks like this:
< Contact FirstName="Bob" MiddleName="Mack" LastName="Dobbs" FileAs="Dobbs, Bob Mack" Company="CoSG" BusinessPhone="866-512-7801" >
Not only are strings like "FirstName" and "BusinessPhone" repeated for every entry, but each person's name is stored twice! And remember, on a handheld portable, file size is more precious than on desktops or laptops.
Why is pseudo-XML slow?
Because XML is a linear file format. If you have 900 entries in the contact list (not at all unrealistic), and you add a new email address to contact #356, then the entire file past that point will have to be re-written. (Unless the programmer was extra-careful and used specialized file-shifting code, which still won't help in all cases). In practice, this meant that Zaurus users with thousands of contacts had to withstand startup or shutdown times of 20+ seconds.
