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. I velcroed it to the side of the case with some hinges so it could flip up when I needed a keyboard lol and, for that purpose, it was perfect!
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 how slim this keyboard is too. PERFECT to slip into a laptop case (although I used it with my desktop).
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. I wanted it small and this one is, too small to use for my main keyboard (layout is too different from what I'm used to so I'm always hitting the wrong key) but just right for what I need.
