Pros: Has every type of port you could need. I like that it has built-in web cam, 802.11n, Gigabit Ethernet, and the fingerprint reader. It's great for lying in bed and watching movies that are stored on my desktop's HD.

Cons: My right palm tends to touch the touchpad when I'm typing. I keep trying to adjust the touchpad sensitivity, but it's still an annoyance until I learn to type without touching it.

Overall Review: Will probably upgrade from 2GB to 4GB RAM because of Vista. I had to download the software for the fingerprint reader from the Asus support site, but it works well. The computer also has face recognition software, but I've had mixed results using it. It would be OK, if you're always in the same environment, but I had problems with it not recognizing me, so I disabled it. The speakers are located above the keyboard... it's not too clear from the pictures. If I could, I would probably swap the video ports on the right side with the USB ports on the back.

Pros: Great value. Collection of just about every feature you could want. Numeric keypad in a 15" machine is great for business users. Light, powerful, great warranty. Get a bluetooth mouse so you won't have to use USB for that (see below)

Cons: USB port location: one on the front, 2 in the back. Easy to bend or break in those locations. Side locations better. High gloss black case - terrible for fingerprints and smudges.

Overall Review: For a high performance model, why not a 7200 rpm drive? Also, XP downgrade option and/or Vista Ultimate option would be nice. Hey ASUS, why are your 14" machines only .25 lb lighter than this one? I've bought 2 of the M51SR for my employees. I'd like a 14" with these features (minus numeric) but with a weight comprable to the competetion.
