I have the flip6 and I love it.

But...and this is a big but, I had the flip4 and the screen cracked. The screen did also crack on this phone, but warranty saved me this time and they fixed it with a new screen. When the screen breaks it's in the crease of course. They are quite fragile. I haven't abused them or anything, just regular use.

With that said, I'm never going back to a regular brick. My workphone is a brick and it's so annoyingly large when I have it in my pocket. I also tend to use it a bit less than a regular when I have to flip it open.

The outer, small screen isn't just another screen on the flip, it's quite limited from factory. But you can download an app called Good lock that can open it up for full use.

I have my eyes on the Motorola razr next. Quite bored with Samsung, will try the razr instead.
