Pros: I like a full sized keyboard. Because this is flexible, it can ride in my laptop case without bother. Some complain about the resistance in the keys, but as a writer, I like having to punch the keys.
Excerpt: Terrible key layout. Editing keys (HOME, INS, DEL, PGUP, PGDN) are placed vertically next to the regular keys, between the numeric keypad and the letter keys. So, every time you attempt to press the Back Space key, you end up hitting the HOME key.
Cons: Terrible response. The keys have to be pushed, not just struck as on a "hard" keyboard, and even then no character is produced about 3 times out of 10. I gave it 1 egg, only because the software wouldn't let me give it 0.
Summary: I bought this to use at school because the existing keyboards are a cesspool of greasy fingerprints, so I carry this with me everyday. It folds up great, works as soon as i plug it in, and it's relatively easy to type on, you just have to move slightly slower to make sure you've hit the buttons...
