For anyone who is considering or interested in upgrading to SSD: I just upgraded my mini with SSD drive. The performance improvement is huge. The machine runs much cooler. It's really easy to do. Admittedly Apple could have made it easyier, but with the right equipment (star shaped screwdrivers) its very easy. Only glitch was on first boot up the mini would chime 3 times and not boot. The problem was my RAM not synced in the slots properly. It took 3 attempts but eventually worked fine. (had to really push hard and click the RAM into place) After booting pressed Cammand R and loaded the OS via Internet. Took about 30 minutes. No CD no serial numbers, really simple. Have to say I'm impressed. If anyone is thinking about it, I would suggest the Vertex 4 - 2.5" - 256GB. I've kept the Ram at 4GB. The machine is used as a media server/player attached to my TV. The computer feels much more responsive. Feels like money well spent and much cheaper than buying the computer with Apple SSD drive. Win!
