Looking to the Future

I would like to upgrade my portable.

This look like a good system: Aspire AS7520-5757

1. Expands to 4GB of memory.
2. Takes the newer SATA drives.
3. 17" screen
4. NVIDIA video
5. Gigabit Ethernet
6. 4 USB ports
7. weight is 7.41 lbs.
8. Price is 699.99 from more than one place.

This is new, but if I can find this system refurbished in about a year or two the price should drop a lot. Maybe down to around 4 to 5 hundred.
