Just out of curiosity, what was it like browsing the web on your M130?
If i remember correctly it had a colour screen but not high-res/high-res+ (320x320/320x480)
Nilsson, for the T5 i dont think the battery life will be too bad as it is somewhat similar to the TX. BUT, it will mainly depend on how much you use it and how long per session.
I REALLY love the TX's battery, can go HOURS straight on the TX browsing the web!
Average day: Check agenda, check net for weather, play games, MP3, notes, games, MP3, browse net for misc., check email and sleep....

+ i can do this for usually 2 days and the battery will be at about 30%. I could also go longer with slightly less use. I've gone 5 days max so far with a relatively large amount of use.
Going by these factors, i would presume that the T5, while not handling the card as well as a TX would, it would still prove to be better than most other Palm PDA's.
