i'm still undecided, i have considered trading for a nexus s
with my evo 4g on weekends and weekdays both i would typically be down to 20% or less by 9pm
my 3d on weekends seems to do way better, i think it was around 35% around midnight last night, but on weekdays when i'm at work it drains like crazy. but work is where i have been experiencing the most connectivity problems. typical weekday so far my phone will be 10% or less by 8pm
also i have noticed if you are playing a game it seems to drain the battery faster than the evo 4g did
It is snappy, but not as snappy as the nexus s.
there are some nice things with sense 3.0. when you are selecting ring tones, you can see what htc has for new ones and download them right there in sense, same with themes and wall papers. there is also a feature to track your phone through htc's website, and you can make it ring in case you lost it. there is a built in task manager, but it doesn't show everything that is running, just apps.
i don't like the carousal, i find it annoying.
the external speaker sucks
i've had the stock camera app freeze on me a few times, as well as the gallery app
i'm still undecided, i know a lot of the issues will be fixed with software upgrades
