I was going to get the new iPhone 5 when it came out, but then I read that it will have a hard-mounted battery, and no expandable memory. Those are two major turn offs for me. And the new EVO also has a hard-mounted battery. So I chose the new Galaxy 3. A few of my coworkers have the Galaxy 2 and they really liked them, so I decided to give it a try.
I got one about 6 weeks ago (Sprint) and it's pretty sweet. It's thinner and lighter than the EVO it replaced, although it's a little longer and wider. I like it. The battery life seems to be better than the EVO, but typical for a smartphone in that you will probably need to charge it every day. I was sorta expecting the battery to not last as long since it's a dual-core processor, but it's not bad.
One minor problem I've had is with the texting keyboard. The text predictions are absolutely WILD sometimes. It comes up with the most ridiculous things! And when you type the lowercase letter "i", it almost always puts in a capital "I"!!! So when you type the lowercase letter, you have to "confirm" it in the little window above the keyboard.

Nice work Samsung. THAT is retarded.
Anyone know of a better keyboard app? I've tried a few from the app store but they had ads that drove me nuts, so I deleted them. I'm willing to pay for it if need be, but I wanna try a free version first.
I bought a few accessories for it.... a screen protector, a very thin snap-on hard case, and a 32GB microSD card. I shouldn't be able to fill that up for a while
One minor gripe is that since this is an LTE phone, it won't work on 4G networks. Sprint won't have its LTE networks up in the Seattle area for about 6-8 months or so, so I have to live with 3G. It's not a big deal, even though mobile web browsing really blows. I can wait a few months.
