Welcome aboard,
I just added a new reply to your post at 1src
I tried to answer your questions in the previous post as fully as I can.
EDIT: copied post from 1src:
-------------------------
I'll tell you what I know.
1. Videos - (Streaming & what filetypes) I don't know about streaming, there is a post about it at OESF. Cacko ROM is your best bet because the kino2 frontend for mplayer plays most video formats. Cacko ROM has an optimized library with a newer kernel, that is supposed to improve movie playback. I haven't encoded any videos yet for 640x480. And your'e best to encode at 640x480, because smaller size videos are said to use extra processing to scale up to 640x480.
2. Music - (Streaming & what filetypes) Again, I don't know about streaming. There is a default music player that plays mp3, wav, (and ogg if you get library).
3. Picture viewing - There are a number of apps for viewing, & editing images. If you want all the image formats, you'll have to get several packages/programs. (most all free of course).
4. PIMs - I don't use them. Default Sharp ROM & Cacko ROM have address, todo, & calendar. Be forewarned though, synching can be difficult, but is possible.
5. Web Browsing - Again, Cacko ROM, I don't know about Sharp ROM. Netfront 3.1 & Opera 7.25
I don't surf on my 'Z', but most seem to prefer Opera. I use Netfront for reading offline saved pages from my desktop box.
pdaXrom includes Firefox, if you decide to use this ROM. pdaXrom is more like a full linux desktop.
6. (Word, Excel, PowerPoint, PDF viewing) - I mentioned what I know above in my last post. (At 1src) I have never used DocsToGo on my Zire 72, so I cannot compare it to Hancom word or sheet.
7. Wireless/BT/Ethernet Options - CF cards, both WIFI & Bluetooth cards. there are numerous cards that work. Make sure to read the forums and find the "Compatable" list before purchasing a CF or BT card.
Ethernet, not sure, but I have read that it's pretty much plug&play with correct card, serial cable, or usb to serial cable.
8. Emulation (Games, SNES Emulators) - there are several of these, and there is a new PSP emulator in the works. I've tried the following. NES, SNES, Turbografx. All seem to work with their own quirks, setup issues. Need to learn keyboard controls, or get a compatable joystick to plugin to USB host.
9. Utilities that make using the Zaurus much more worth while - Many, that's up to you. there are lots of utilities, filemanagers, ect. Cacko ROM comes with a slew of utilities.
10. Overclocking - Again Cacko with newer kernel. battery applet has 3 high and 3 lower overclocking features. I've not used them, but are said to be stable and people seem happy with these settings.

I hope this answers some of your questions,
