The units do not get 8 hours on time even with the big battery on Wifi. As to Word, etc. I ran into someone who thought they would use that instead of a laptop. I warned them off, but 700 bucks later it sits on their desk as an ornament. I hope you are not thinking of using it to craft documents.

Ok, first question:
Under NORMAL REAL-WORLD USE (not playing movies/mp3's/mega-tasking all at full volume all the time) such as sometimes being wireless, sometimes playing mp3's but mostly using Outlook/Excel/Word, what kind of difference will I see in the battery life between the two units with both the standard battery and/or the big battery?
Next Questions:
Considering there are 2 different types of expansion cards that can be used, can
1) both slots be used simultaneously? and
2) Which slot should I use for memory vs/ expansion? I guess what i want to know here is if one type of media is faster for file accessing and which slot will be more useful to keep open for games/gps/other expandability options?
Thanks!
