I'll keep my device for a while. The longer I drag it out, the cheaper an upgrade will be. I like the Evo 3d and all, but really, in six months there will be something faster, and in a year quad core phones will be hitting the market. I went through this pissing contest with computers a few years ago. I won't do it again.
So, any device I like must have a few requirements before I buy now.
1. Stability. In terms of hardware and software. I'm thinking light leak and screen lift here.
2. Support. If I get a 3d or another 4g device, I had better actually be able to use it. Not as a con, or a wow factor, but actually have a need to use the feature.
3.Aftermarket accessory support. It took the Evo how long to get any decent cases? The Otterbox Defender pretty much sucked and so far the only case I found worth a damn is the Ballistic HC case and that too took quite a while to surface.
