I just got a new Evo 4g as my work phone and it is awesome. I haven't had one problem out of it and the battery lasts all day and then some. It can be a wifi hotspot as well, so I can be about anywhere and have internet on my laptop.
I can tell you it made me want to switch from the iphone to it as a personal phone. I haven't yet, just haven't had time, but probably will.
