So I decided on the Thunderbolt. Had it 4 days now. I love it so far. Granted, this is my first smart phone so I would have been impressed with anything, but I didn't expect so many options and this good of performance. I keep thinking, 'what can it not do?'
It is very fast navigating around, and running applications. The downloads are very fast too and I'm not using Wi-fi and only 3G. I've been going jogging listening to Pandora and Slacker, no problems yet in lag or skips. I've also been using my laptop through the mobile hot spot feature and it seems to keep up as well if not better with multiple streaming videos than my 6meg cable modem at home! I did not expect that.
I'm still messing around with it, trying stuff out, getting it set up. I'm trying to keep apps to a minimum to save on processing and bandwidth because I don't want to diminish this awesome performance with a bunch of useless crap I'll rarely, if ever use. For instance, email accounts that I don't check often I access through a browser. Same with Facebook, skype, etc.
Only complaints so far, other than some occasional hiccups {which I suppose is to be expected} is the battery. It burns up fast! I'm looking to get a slightly bigger after market battery, but not the extended. That thing just looks hideous! Otherwise, some phone call quality hasn't been so good, especially during app downloads. Not sure yet if it's the network, the phone's reception capabilities or has more to do with the people I've been calling. I honestly haven't been making very many phone calls with it at all. ;P
Best investment I've made in a long time as far as I'm concerned.
