Pros: Adds a very nice BlueTooth sliding keyboard case for the iPhone 4. Has a backlit keyboard. Very easy to set up. Has a nice spring when you slide the keyboard out. Solid battery life.
Cons: Doubles the thickness of the your iPhone. The keys could be more prominent and distinct.
Overall: This is the best keyboard case on the market. All keyboard cases are going to make your iPhone around two times thicker, so why not go with the one with the best keyboard, and tactile feedback?

Pros: Keeps your keyboard clean, quiets keyboard clicks, patent pending key mold design
Cons: loses shape after about a month at the bottom edge
Overall: The Verco Silicone keyboard skin will fit both your Macbook keyboard as well as the Apple Wireless Keyboard yet I really wish it kept its shape a bit better on the bottom edge.

Pros: Super fit, keeps your keyboard clean, actually quiets louder clicking keyboards, hardly notice it’s on.
Cons: Need to purchase from the companies eBay store, after about a month the skin starts to bow a bit at the front edge of the keyboard, a bit pricey at $18.
Overall: The Vecro Silicone Skin from Rearth USA does a fantastic job of protecting your keyboard as well as quieting loud keyboard clicks.  I enjoyed using this product during my tests. The one disappointment was that after about a month the leading edge near the spacebar started to bow up a bit and became annoying.  I also would like to see this products priced a bit lower than the current $18 price tag.

Pros: Easy to type on, fits the Mac look very well, 3 year battery life, extra function keys, Logitech Control Center
Cons: Hot keys with the eject button do not work, such as Sleep (Command + Shift + Eject), glossy black design will show off fingerprints
Overall: This will be a welcomed edition to any Mac setup. With Logitech control center setting function keys to your preference is just a few clicks away. The black and aluminum make it look right at home with recent iMacs and Macbook Pros. If you are able to pick this up on sale I highly recommend this keyboard, so much that I’ve decided to award it the Editors Choice award.
