I tried the Samsung Captivate for a couple of days, its a very promising platform, but I think it still needs some re-working,

Battery life was horrible, I was 40% by lunch time.

Also it seemed that every couple of days I would have to re-boot to get it to operate at its original fast speeds.

So I brought it back and got an iphone, then I "Jailbroke" the OS, and now I have the ultimate phone, for now
