well, any handheld devices running windows mobile edition should allow those capabilities. Nowadays, most pda's or smartphone allow that anywayy, even my Nokia 7710 mobile allows me to view/edit/and create MS Word and Excel files!
If that LifeDrive was a PDA phone, I'd be sold. Why is it you can never find all the options you want/need on one device? I just opened a new thread requesting reviews on a couple PDA phones although neither one has all the options I'd like.
