I think the SZ series needs a reboot when you need to switch GPUs from the 8400 to the X3100...
There's a similar deal online at Sony's official site for a newer SZ 7 series with 2.4 GHz Penryn, 3 GB RAM, 160G HDD, hybrid GPU, ABGN, extended battery for $1600 flat with free shipping...and you can configure it yourself (it starts at 1400 ish)...might be just a little better than this older SZ6 on amazon.
