Well, I have given my Z (SL5500) to my brother... so I have no Zaurus anymore. Had it for about 1.5 years previously, loved web-surfing with it. I now have a Tungsten C (gift from brother)...
Here are some thoughts about the Z, as a general/mass-market PDA (in case I want to go back to the Z... here are some things I would try):
Complaint: No commercial content, e.g. ebooks
Possible answer: Get MS Reader format ebooks and convert to OpieReader-compatible format.
This would resolve most complains about ebooks: you can get all the latest and greatest best-sellers this way. You can even get specialised ebooks (e.g. medical, dictionaries, etc.) in MS Reader format and use it this way.
Complaint: Lack of specialised commercial content, e.g. medical resources (e.g.
www.skyscape.com)
Possible answer: A lot of free available resources, such as Merck (
www.merck.com), which you can convert using Plucker. (The whole Merck 17th Ed. is 100MB) Or
www.pathguy.com, or the likes.
Unfortunately, it is true that this is not the best answer, and unfortunately, the commercial content (e.g. from skyscape) is of higher quality. But it can do. Medical dictionaries are also possible.
PDFs can also be made on the desktop, and qpdf or equivalent can be used on the Z.
Complaint: Lack of good PIM.
Possible answer: Frankly, the built-in PIM is *adequate*. Not great, not fantastic, but adequate. It gets the job done. I used it, together with tkcDateBook in the past. The tkc apps are *okay* only, as well. One possible answer I have never tried: use an X-based ROM (e.g. pdaXrom) and install some good X-based PIM (forgot which ones were mentioned in some threads... someone can help here!)
Complaint: Lack of good Office apps.
Possible answer: Many appears to think the Office apps are okay. I found them to be abhorrent! All formatting are lost, worse... if you load the RTF, modify it in Word and save as RTF... all kinds of new/weird formatting appears. You better save it as Word format and reimport in HancomWord. Then, it works better. I even purchased HancomOffice for Linux thinking it would help, but nada... both are pieces of junk in my opinion.
AbiWord on pdaXrom is a possible answer: at least, you have a desktop equivalent that supports exactly the same features --- no formatting lost from Z to desktop.
Perhaps, one possibility is to get BasiliskII (mac emu) working, especially on pdaXrom (don't think Basilisk exists on that yet), and then run MacWord 5.1 or WP3.5? The old MsOffice6 or ClarisWorks that work on MacOS7.x should also run in there...
Complaint: Lack of synchronisation with desktop.
Possible answer: Wifi/FTP whatever you want to backup. If you are using pdaXrom with desktop apps, you can just FTP over the files and use them on the desktop, or with minimal conversion. This is a "flatter" and simpler synchronisation actually, and can work very well. Scripts might already be available or can be written to do automatic sync/scheduled syncs. There is guaranteed no ActiveSync problems, or sudden, unknown errors that stop you from syncing anymore.
Complaint: Lack of synch with Outlook...
Possible answer: well there... just don't use Outlook! Frankly, if you are so stuck to MS, just get a PocketPC! In the end, there is no way out: e.g. if you have a precondition that you must use Windows Mobile as your OS, you can never get a Z for that, or if you could, you should just get a real PocketPC, e.g. Ipaqs. You can choose Thunderbird, or Firebird with pdaXrom, and use the same on desktop. Probably can help in the sync.
Well, those are just my thoughts. I think the Z can become quite usable. What do others think?
