It's a great overall machine!!!!

I bought this one to exchange the 2 defective Acer units. Too bad I did not buy Sony in the first place. The notebook is Made In Japan, and compared to chinese Acers it's like comparing Ferrari to Echo. Acers build quality is very questionable. The feel is solid, the size is very compact, the performance is far beyond what a mobile user usually requires, one can play Far Cry on this machine with NVidia 128 6200 card installed.
The battery lasts about 2 hours when watching the DVD and longer when just using Word or browsing the net.
The screen is the best I've seen, very bright and crisp.
I comes with Sony pre-installed software, many of which are indeed good, however, I replaced quite a few with my choices.
Drivers and utilities are available from the web easily. I even updated the BIOS on the first day and it was a bit scary:)

Overall - very very good machine! Recommended!
