Pop, glad to hear you have come back from the knife.
Is your old machine full of important items? Or are you free to abandon it and move on to something new?
I generally get a new machine each year, or sometimes more frequently. This time it is a chromebook, which is great for browsing, with superfast boot-up and high speed wifi. After W7 you could well find it refreshing to have a low cost high performance device. Unless of course you need really serious computing stuff.
Keep on truckin'
