I hate folding keyboards. In fact, I mostly hate anything smaller than an Apple Keyboard or the Logitech K811 that I do most of my work on. Anything more compact and you start to see compromises--key size and spacing are reduced, funky key layouts that your fingers will hate are used and sometimes, important keys that we take for granted, like music pause/play and volume, are removed all together.
I like to think that this loathing I hold for compact and folding keyboards makes me a good choice for reviewing them. I type for a living. It takes a lot to impress me. For this PC World roundup, I'll tell you right now, I was largely unimpressed. That said, there were a couple of keyboards in the mix that, if I had to, I could live with.
