Seems nice. I just wish it had removable battery, like phones used to, so I could carry a spare around, like I used to with Sony Ericsson W200i.
Also dedicated dual SIM + MicroSD instead of hybrid.
Just got an idea, the Galaxy Flip has 2 batteries. Small one, and large one. What if there was a small one built-in, and a larger swappable one. You could then hot-swap the batteries like with some ThinkPads (those with internal + external battery).
