I've had an HTC EVO 4G with Sprint since the middle of last year. I fell in love with having all this information at my fingertips. Not too long after realizing that all this power comes at a cost to the battery life, I bought an extended battery.
I'm always checking my email and browsing this forum, OS, even realgm sometimes and checking out spikednation, a youtube filter site. When my mp3 player breaks down, I can connect to my home computer through my phone and play mp3's straight from there, or just listen to pandora and their wonderful ads.
Even though I got pretty good at thumbing my text messages or any other text input, I can't go back after using Swype. Just slide your finger from letter to letter and it types out the word. If your lazy, you can just hit the voice to text button and say what you want to write, and it will convert it.
I have all the Angry Bird apps, including Rio, which is the best of all of them, imo. I have played games such as stellar escape, stardunk, spiderman, sandstorm, deathworm, contra 4, asphalt, and a few others. I don't think I am much of a serious mobile gamer since I rarely finish them. I guess angry birds makes it a bit easier since you can just load it up and play a couple levels at a time.
Netflix and now HBO GO provides plenty of movies and tv if I need some entertainment while I am out, especially since I can hook an hdmi cable up to my phone and play it on a tv.
Having an HD-resolution camcorder on it is really handy, as I can catch moments like
this. I find Android to be awesome as a platform, especially with all the custom ROMs. That's right. If a new phone comes out, there are chances that it's software features can be modded into a rom and you can put it on your phone. Don't like your manufacturers customization and bloated apps that you can't remove? You can go with a base android rom. I never went farther than rooting the stock rom. Everything on my phone worked the way I needed it. Any problems that came up were easily searchable and most often they were common, so others may have already found a workaround, or the manufacturer or carrier made an update.
This thing makes phone calls, too.
If you have a smartphone, whether it is an iphone, android, or a windows phone, what do you enjoy doing with it?
