So some first impressions (over the first few hours):
1. It was easy enough to get the new phone started up. Just swapped the SIM card, and it took about 10 minutes before I could dial and receive, but looks like no problems there.
2. Had to re-download all of my apps, but it was just sitting there, redownloading. It's not like I had to walk 10 miles through the snow, uphill, to get them.
3. Docs, photos, etc transferred with a breeze.
4. Have not tried to move any music, but I may not. I still have my iPod for that.
5. Group texting is not possible through the standard, pre-installed texting app, which kind of sucks. Mrs. Hawk has always said that was an impediment to her going Android (she's a texting machine, it's all part of the the Northwest Harris County Barbie Collector's Cheap Wine and Cigarettes Club, apparently), but I downloaded Textra, made it the default text app, and all seems to be going swimmingly.
6. For the most part everything is fairly intuitive, and it is quite customizable.
7. Battery life seems to be OK, but I'll know more as the days wear on.
8. There is a large amount of shit at the top of the home screen that I've yet to figure out. I suppose I will. It does come pre-installed with a lot of google shit, but it's not too onerous to remove.
I'm sure I'll have more to bitch about later. But I'm liking getting this level of performance in a non-plastic phone for about 30% of the cost of a new iPhone.
