T-Mobile Dash (HTC S621). If ever there was a phone that was non-touchscreen and could hang up at the drop of a hat, it was that POS... I didn't care for my MDAII or the Palm Pre I test drove but I still despise the Dash. If ever there was a phone with a worse keyboard than a Centro, it was the Dash. When I see one on the street I just wanna slap it to the ground, grab the owner by the coller and shake him while yelling "Hey, what the F*#K are you thinking, wake up!!!". So yeah, I kinda hate that phone.
Motorola KRZR, the most buggy horrible phone ever! It literally had to be re-flashed to Verizon firmware every couple of weeks or else it would become stuck in an infinite freeze loop. It looked pretty good though, until the front glass developed a nice, big crack. :/
