Ive gota Advent Stainless Steel Keyboard, full size, but buttons the same design as laptop ones. Very thin. Ive experienced very few problems.
Gaming Keyboards Are Worth it to many people - but not me, They often have around 12 Button press limit, the buttons are more sensitive, and they usually have faster response times, such as 1Ms from razers hyper response technology, comparing to 8-16ms of conventional keyboards.
