in all fairness, i did not know what model you were talking about and i stated clearly in my thread i was comparing the 800w to the 8330 and BB storm. not to the 8320.
so your weight differences doesn't apply to my argument in which i compared 2 BB's to the 800w, just not the certain model you had. as for the 3.5 jack, i don't know about the majority of users but i have since switched to bluetooth to avoid cords and would have never used a 3.5mm jack on my phone anyways. To me its like an A: floppy disk drive on computers....took awhile to get away from them but people stopped using them.
i also use google maps mobile (free application btw for everyone) and since the treo 800w has an internal gps chip, i use satellites for position and the internet on the phone provides things like phone #'s and reviews for resturants if that is the thing that i'm looking up directions for. i guess UMA would work in an urban setting but there are deadzones and seems like UMA would not keep your GPS tracking in areas where you would not get cell phone reception. also, i'm on the unlimited sprint SERO plan for $25/month after certain discounts. although not everyone can get that deal, not everyone can get your unlimited $60 plan either. so for $25/month, i can do without push email. i was under the impression that most, if not all cell phone providers required a Blackberry Internet Service (usually around $25-30/month) to be purchased along with the phone if you wanted to use it to its potential. last time i checked this was the case for verizon, t-mobile, rogers, and sprint. if i'm wrong then please forgive me. hope all this discussion is helping the OP! lol.
either way OP, seems like people are happy with their choices so you would probably too.
