I want to, and wish I could wait out the problems, but my laptop can barely play YouTube videos anymore. I've ran tests, deleted software, and updated to Windows 7 but nothing seems to help. I have to restart it two ar three times a day. Any website that uses Flash is likely to make it freeze because it's too taxing on it. I ran a GeekBench test on it the other day and it got a 1138. That is LOW. It's on it's way out. My desktop died a year ago and I have no backup option if this decides to up and quit on me. I will have a bunch of POed clients if that happens.
Still, it is a SAD reason to buy an iMac! Did you try to do a clean install??
