Excellent board, not exactly simple though. All I wanted was a decent backlit board, but there's simply not too many of those around.
Macro keys are easy to use and program. Handy to hold an e-mail address or password, if you feel comfortable programming a password into it.
Cons... I guess be carefull not to scrape anything on it: the paint can chip off, but that hasn't happened here yet and I've been using and moving it about a fair bit. And it lacks some of the hotkeys you find on simpler boards, to open a browser or media player for example. (does have prev/next, pause and stop for WindowsMP + volume control and mute button)
Bit overpriced considering you'll likely only use half of it (features that is, not keys

). Stuff like the build-in soundcard and ports for a headset, and I don't even use half of the macro keys. USB port goes unused as well; thing to note: it's low powered. Can run something like a mouse of it, but don't go plugging in a USB harddrive or something.
