if you want the garnwt vm, will give you 2 way palm sync over wifi with your pc. I use ermining with the gpe suite. it's one way but hasn't become a problem yet (google cal). as others are pointing out video time is dependent on video type. I have video that'll kill the battery in 10 min. On another note, reading your wish list, you'd probably do better with a iPod touch , especially if your going to find yourself re-encoding video anyway. That's heresy around these parts though.
