Pros: Super fast. My Applications are sitting on the SSD; they run about as fast as I can click to launch them. Parallels can cold boot a Windows 7 VM (on the SSD) in about 5 seconds (literally).

Cons: There's some headache setting up TRIM for non-Apple hardware. But really it's about as simple as downloading an app and flipping a toggle to enable it for third party devices.

Overall Review: The other hang up, naturally, is conserving space on the expensive drive. This one is large enough to run all your downloads, music, games, etc, but I bought a caddy and moved my 750G to the DVD bay. I setup symbolic links for Downloads, Music, Movies, Pictures and a Parallels VM area. Those directories don't really need a lot of performance and are used mostly just for storage. I did want most of my Home directory on the SSD though because of the ~/Library directory and other smaller documents that will keep things running fast. I also put the rest of the system including /Applications on the SSD. This is what you're paying for. I can boot Mac in about 10 seconds from a cold stop. My VM's on the old HDD still run the same as usual. I highly recommend this upgrade in combination with the drive caddy.

Pros: cheap and functional. It works well in quiet, sound absorbing areas.

Cons: lots of background noise.

Pros: Sleek cool design; just like my old one. Laser part is cool; it works on multiple surfaces that my old optical one didn't.

Cons: maybe mine is a fluke, but my left mouse button feels like it clicks twice. This is immensely annoying. I think it has something to do with the plastic form of the chassis.

Overall Review: My old mouse was the exact same design; just the older optical version from several years back; slightly different color. I had no problems with it, so I'm thinking this might be a fluke...
