Well, since TsingTao asked, here is what I'm looking for in a PDA (warning: long!):
The following list is what I’m looking for. I intend to rate devices on a 1 to 10 scale (higher is better), and each category has a multiplier for how important it is to me.
1. Cost x 10
- I am frugal and want good value for my money. I’m thinking of spending around $300 for the system and attachments (media card, keyboard).
2. Reading x 10
- One of the primary uses of this device will be for reading.
- I would like to be able to read .txt, .rtf, .html, and .pdf files
- Support for .ps and .doc files may be nice
- I’m unsure where I stand on proprietary e-book formats
- I would really like of screen resolution of 320x240 or greater.
3. Linux Friendly x 9
- I need to be able to transfer files and settings and do development work from a PC running Linux. I don’t want to have to boot into Windows to use it!
4. Longevity x 8
- I want a quality product that is not likely to break; one that is rugged and long lasting
- I want a product that can be replaced (if stolen), such that I can continue to run all my software. The replacement can be another of the same kind of unit, or a backwards compatible successor.
5. Writing x 7
- The ability to enter text quickly and painlessly is important [not that I expect it to be as easy as a PC]
- I’d like to be able to jot down notes, draft e-mails, write poetry …
- I need to be able to save what I write and transfer it to a PC
6. Coding x 7
- I want to be able to write my own applications for the system (and cross-compile it)
- I would also like to be able to write code on the system (and interpret or compile it)
- I’d like the device to be happy with people doing homebrew, and I’d like an active, friendly homebrew community to participate with
7. Battery Life x 6
- The unit needs to be able to handle 2.5 hrs of use while commuting each day
- It needs to be useful for long trips
- The batteries must be rechargeable; it is useful if I can have a second battery charged and can swap a dead one out
8. Audio x 5
- I want to play .ogg music files
- I’d also like to play speex encoded files (which I think will be great for conference talks or books on tape)
- I’m not interested in DRM-laden formats (.wma, .aac)
9. Network Access x 5
- It’d be nice to surf the web, transfer documents, do SSH, remote desktopping …
- I don’t have any WiFi or Bluetooth devices, but I think WiFi is the way to go
10. Useful right now x 5
- If I can use it to do these things right now, rather than wait for / writing applications for it, so much the better
11. Games x 4
- I’d like to have interpreters for playing text and graphical adventure games
- Emulators (SNES, Apple II, …) would be nice
- I’d also enjoy being able to play (affordable) commercial games
- I am not interested in piracy
12. Hackability x 3
- I’m a hobbyist robotisist, and would love to be able to hook my system up to other electronic devices (such as keyboards, PCs, microcontrollers …)
13. Portable x 3 [Doesn’t count much because it should be a given]
- It needs to be useful on a bus! (This is where my laptop falls down – I’m too scrunched up to type when on a bus)
14. Anti-Microsoft x 3
- I’d rather not give MS any more money or mindshare
Thinks I don’t care about:
- Watching movies
- Taking pictures
- I’m not a mobile professional; I don’t need to send e-mails while on the go; I’m not worried about scheduling or contact synchronization, and I don’t really need an organizer
---------------------
I figured [and I was quite possibly wrong] that I could go two ways -- with a PDA that runs games, or a game machine with some PDA functions.
Devices I was going to look into:
- Sharp Zaurus 5500 [Discontinued]
- Tapwave Zodiac [Discontinued]
- Nintendo DS
- GP2X
- Palms and PocketPCs
I have done some poking into them (but haven't looked at them all in depth.) It appears that the Zaurus is what I want. I ranked it as follows:
-----
Sharp Zaurus 5500 [Discontinued]
Specs:
206 MHz ARM
16 MB ROM
64 MB RAM (Program memory and data memory)
CF and SD slots (and add-on cards)
IrDA
Stereo headphone jack
Built-in keyboard
Touch screen
320*240 reflective TFT @ 16 bpp
1. Cost: 6
It is hard to tell if I can actually buy one or not. I’d probably have to get it off of e-bay.
$325 - Looks like I can get a refurbished one with WiFi for $250 US at
http://linuxwebtool.com. I don’t know what the shipping is ($20?).
$20 - 128 MB CF card
$20 – Flash card reader
---------
$365 [or less, from e-bay or possibly other sources.]
2. Reading: 10
Has a web-browser; can read .pdfs and e-books
Resolution: 320*240 – excellent.
3. Linux Friendly: 7
I don’t know how friendly it is out of the box, and it sounds like there may be syncing issues, but with different ROMs installed it is fairly friendly. I can certainly cross-compile from linux.
4. Longevity: 3
I’m not even sure if I can get one now, much less get one later. [Although, if I’m willing to pay a ton of money and import from Japan, I can probably get a newer model.]
5. Writing: 8
Built in thumb-pad, limited hand-writing recorgnition with touch screen.
There should be word processing software available – it appears that there are lots of broken links.
6. Coding: 10
Can cross-compile on PC; can compile on system, runs python and perl!
7. Battery Life: 3
Sounds like it isn’t very good.
8. Audio: 10
Plays .oggs (out of the box!)
9. Network Access: 10
If I get a wifi card (and have a wifi network), it will do all things I could hope to do on a network. (ssh, web browsing, VNC …)
10. Useful right now: 10
11. Games: 7
- tons of emulators, including NES, SNES, Apple II
- interpreters, including ScummVM and FreeSCI
- I don’t believe there are commercial games (and if there were, I probably can’t get them now.)
12. Hackability: 6
Didn’t look too deeply, but it appears to be (hardware) hackable.
13. Portable: 10
14. Anti-Microsoft: 10
My final rating for it was 647, out of a possible 850; it averages 7.61 per category.)
The 5600 appears to be like the 5500 but better -- faster CPU and longer battery life. If I could get it for a good deal, then it would be the way to go.
