Clamshell Sharp Zaurus Reviewed
Bill Kendrick writes "The Gadgeteer has a review of the new clamshell-style Sharp Zaurus SL-C700 Linux-based PDA. This new model, currently only officially available in Japan, sports a larger keyboard than the SL-5500 we have in the US, as well as a full 640x480 screen and 400MHz XScale CPU. The review mostly compares it against the HP200. The reviewer got his hands on an 'English version,' made available by Dynamism for a hefty pricetag of USD$700." (See this earlier story for more screenshots from the English conversion of this device.)
A review that does not focus on the lack of English documentation (the most irrelevant thing when discussing a product that as of now, is only released in Japan) sums it up:
The Zaurus SL-C700 is an impressive PDA that departs from more traditional designs. The stellar display, mated with a comprehensive software suite, definitely impressed us and we look forward to production-level units of the C700. Pricing is estimated between $600 and $700, though that may change at the time of release.
This device could really be a breakthrough device with the cool form factor, great display, and mainstream Linux support. I urge anyone who is interested to write to Sharp and/or post on the above forum. Don't let Sharp fsck this opportunity up...

oups... sorry, I mistyped :

- The going price in Japan for the SL-C700 is a touch under US$500 (if you can get any, that is; it's still in short supply, two months after release). Dynamism is getting a hefty margin for their effort.
- Battery life is one of the biggest problems with this unit. The biggest battery drainers are the LCD backlight and the CF card. If you keep the backlight dim (which is adequate if you're indoors), and you don't have a WiFi card or a wireless modem running, you can easily exceed 3.5h in battery time. If you go full blast on both, the battery life can be as low as 1.5h. If you want better battery life, a better solution would be the SL-6000 (sold as the SL-B500 in Japan), which doesn't have the nice display, but whose battery lasts as much as 18 hours.
- Memory is the other big problem. Actually, you can get by with 32MB of RAM if you turn off "resident in RAM" flags for the commonly used programs, but then you have to wait a few seconds every time you want to use them. Many Japanese users have resorted to creating swap files on SD cards. For some reason, Sharp is refusing to acknowledge this as an issue.
- The machine does feel a bit unresponsive, especially when starting applications. This appears to be mostly due to the toolkit (Qt-Embedded) and the unaccelerated framebuffer. OTOH, profiling reveals that a lot of time is wasted opening and closing huge Japanese font files on startup, so maybe the English version runs much faster.
- Sharp does publish kernel code, in accordance with GPL (although the SD card driver is proprietary). However, the QtE code, as well as most of the PIM code, is proprietary, which means that the users can't do much about the above problem. (Sharp's engineer said in an interview that recompiling the stock QtE library from Trolltech will likely not work.)
- Sharp's decision to make 802.11b optional makes perfect sense in Japan, because hotspots aren't as ubiquitous or interoperable here as they are in the US. The most popular PDA wireless solution here is a cell phone modem in CF form, which works in almost all urban areas at 32kbps-128kbps. And if you do need WiFi, what's so hard about plugging a modem in?
- Yes, third party application support is pretty patchy--unless you can live with console applications, in which virtually every non-X applications in Debian is a recompile away from running on the C700! A lot of Japanese users who were fed up with the default mailer are now happily using emacs to read their mail, for example.
To me, switching from the Palm Vx to the SL-C700 was like trading in a middle-aged accountant for a teenage math genius. The Palm was clearly better at traditional PDA work, and doesn't drive you up the wall like the C700 does sometimes, but there is something unquantifiable that is truly exciting about the C700 that the Palm can't begin to copy.The prices at Dynamism are a bit on the high side in my opinion. I purchased my SL-C700 in Japan at Yodobashi Camera for about 55000 JPY which at the current spot rate is about 460.00 USD.

Presumably part of that is to recoup shipping and some of the translation costs but a lot of what you are paying is for the after-purchase Fedex replacement service should you ever break the unit.
Short of hopping on the next plane to Tokyo, one alternative is to order one from Conics for 569USD. You may then switch to SL-C700 (mostly) to English yourself by adding the line:

I currently have one C700 sitting on my desktop for a review. I also have a Sony Clié SJ20 (for old palm medical ebooks I can not read on the Zaurus due to DRM - no matter I *purchased* them I can't legally do what I want with them but that's another story) and a SL 5500. I also had a SL 5000d before, a Clié NR 70, a Clié 760 and various Visors.
...
The C700 is a killer - first it feels so cool! I can't remember being so impressed by a PDA except maybe by the Clié 760 which was really innovative for its time. The C700 can really hold in your shirt pocket - honnestly it's as small as the smallest clié available only a little wider. The screen is a pure marvel - forget the cliés or the ipaqs. I know I don't need color but when you see such a beautiful screen you realise can't live without it.. Just plug your CF in and show your digital pics to your friend on a real screen ! Or use the embedded web browser which can load real websites (no downgraded avantgo like stuff), uqtreader (http://www.timwentford.uklinux.net/) to read offline channels or P.Gutemberg ebooks,
The keyboard is big enought for real typing and the battery life is not a problem (~ 4h in a row? That's more than most color palms and pocket pcs!) since the charger is as big as a tic tac box. And I can afford a spare battery and an external charger if I really need ~8 h in a row.
The real problem is that most software written for the 5500 uses fixed sizes in pixels for a 240x340 screen - that does not scale well on a 640x480. Layouts *should* be used !!! And the emulation for 240x340 takes ~5 sec to load - forever if you need the application *now*. That's not a problem since most 5500 apps are GPL'ed so you can fix the code but if you are using poorly written commercial software on your 5500 forget it !
Moreover the memory is somehow limited : you can't launch many apps at the same time, especially memory hogs like java applications.
It is really promising once a) more software will be ported or cleanly coded and b) opie (http://www.opie.info) will be ported, allowing to put the root filesystem on a SD card thus keeping the while 64M of memory for the system.
If you have $700, if you don't mind replacing the pim by other software (PC syncs sucks - and for some reason they decided to drop the XML format from the PIM) do yourself a favor a get one. In some weeks you will be able to use Opie free software distribution and get the real power out of this baby!
Please check my C700 forum http://externe.net/zaurus/forum if you have one and need some help.
