I got the keyboard cover today, and have to say it's a bit of a gimmick.
1: There is no dedicated full stop button, you must hold alt, then press full stop as it's a secondary character.
2: It's trying o be BlackBerry, but failing at basic BlackBerry wins, like when you press space on a URL, I want it to autofill .com/.co.uk etc. Space just enters a space in URLs. Pointless.
3: Screen rotation cannot be turned on when the keyboard is in use.
4: It's QWERTY, but the symbol and character locations are not standard layout, so you need to become familiar with that.
5: If you've set the navigation bar buttons to the correct layout, then attaching the keyboard resets it, and won't restore your preference when detaching the keyboard.
6: Keys don't illuminate, so it's useless in the dark. This is an AMOLED phone, Samsung should have put holes on the underside so that "on" AMOLED pixels illuminate through the keycaps, and you could customise what colour they light up. Perfect or gamers too. How cool would that have been?!!
The case itself is pretty good though. Offers little front protection of course, but feels good, and is of excellent material quality. If anything, it's a super slim case for those who don't want finger prints on the back of the phone, or scuffs and stuff.
