Just want to put in my 2 cents for the folks asking if mechanical is worth having. Though I am not sure this deal is the best deal around.
If you want a inexpensive Mechanical Keyboard the M10 isn't horrible (50-60 dollars). Not particularly well made compared to some other Mechanical keyboard but if you don't want to spend 100 dollars not a bad board.
The best place to read about mechanical keyboards is this thread:

I personally won't ever use a non-mechanical keyboard if I have a choice. I have had ALPS Black (ABS M1) and Cherry MX Brown and Blue keyboards,ThinkPad laptops, Dell laptops and regular membrane keyboards.
The ABS M1 is a horrible keyboard I feel because it was loud and ringy and required way way too much force to use. At least mine.
I have Noppoo Choc Mini 84 MX Blue and and iOne MX Blue M10 and Ducky MX Blue.
I had an MX Brown which is tactile but not clicky. For me it is mostly about the click. The auditory feedback helps with touch typing. So does the tactile feedback. I only type about 80-90 WPM but I still think it is one of those things if once you use one you like it you won't go back.
The general rule of thumb is Brown or Black for games and Blue if you just want to type. I just want to mostly type...
