1) Yes, I currently own an SSD. Will plan on buying a few more in the next few months.
2) I''m considering Intel, but other brands are okay as well if the price is right.
3) I purchase the new PC every 3-4 months.
For personal use that Acer would be fine. I would highly recommend 2gb of ram since Vista can be slow with 1 GB. If you plan on playing new 3D games, then a laptop with dedicated video card would be better.
I don't think that is a good price for a laptop, especially the cpu (Sempron). For that price I think it's better for you to go to Staples and buy a laptop with some kind of dual core cpu. Plus they also offer a free printer after rebate.
