I am on my second Vista. My computer has a drinking problem. Had too much wine in the key board. I wanted a Mac, but could not come up with the cabbage. Did a little more research. Buy all the ram you can get. Stll need to be around $800.00 - $1000.00. My other computer struggled because Vista prettty much had it maxed out. That's why they want to lock-up. My new one is an HP. So far very pleased, however if you can step up to the plate...Go Mac.
