In regards to the Aspire 1800, you can find details on this notebook if you look hard enough. In my opinion, it does not seem that impressive and definitely not a direct descendant or competitor for that matter to the Aspire 1710. It uses notebook memory, notebook hard disks, and a 17" widescreen 1440x900 display. This is entering a crowded market, whereas there is nothing else out there like the Aspire 1710 (17" desktop LCD, 3.5" hard disks, desktop memory, etc.)
It does use PCI Express Mobility Radeon X600 with 64MB (this chip is essentially the equivalent of Mobility Radeon 9700). Also, the GeForce FX Go 5700 and Mobility Radeon 9700 are essentially the same performance and feature wise. Unless you just have to have ATI, there is no reason to get this chip in my opinion.
In any case, here is a link to the notebook on Acer UK.
