Pros: Solid little keyboard. No issues performance issues at all. Own two, have one hooked up to my PS3 other on my computer. Buttons still all respond perfectly 6 years later.
Cons: Backspace is smaller than normal keyboards, that's not the con... the backspace key shares space with the home key and I had to remove the home key because I kept hitting it when attempting to backspace. Now, with the home key removed, con fixed.
Pros: Compact, portable, and reasonably durable. It's got full-size keys, and it hasn't dropped or badly re-positioned any of them in the name of size.
Cons: The NumLock key controls whether the right-hand side of the keyboard is letters or numbers. Since most computers start up with NumLock on, you need to remember to turn it off before you start typing.
Summary: This is a great little portable keyboard. I dropped it and it didn't even break. Cheap and pretty good quality. I like the sound of a cheaper keyboard for some reason. Only downside for me is the size and position of the left ctrl key.
Summary: The keyboard layout has some common keys such as delete in unusual places. But then I bought this for use together with an HTPC, so small footprint is the highest priority, I can live with the weird layout since it's used very infrequently.
Summary: I recently (today, actually) upgraded to the Adesso MCK-91 for the fancy media buttons, but I'm still keeping this guy in my parts storage. I originally bought this keyboard for a (failed) custom laptop project (don't ask) because it is SO thin.
Pros: I absolutely loved this keyboard while I was still using it. The layout is so compact you can hit the home or end keys while holding shift and cntrl with no problems at all. The layout took about a week to get used to, but once I had it down, my fingers were blazin' on those keys lol. Gotta love ...
Cons: Control wasn't the last key on the bottom row, which took some getting used to.
Summary: Its exactly what I wanted, small keyboard to use when working on friends computers using the tv as a monitor. PS2 is nice for older machines that dont work with usb during boot for bios upgrades or booting to dos.
