I got tired of constant problems with my GateWay PC...it now sits in the closet, maybe someday I'll have it reprogramed. I was using Registry Mechanic, and a few others...a lot...still had problems.
I bought a new iMac...it's coming up on a year now...never a problem. I liked it so well that I bought a second one for my wife about 4 months ago. Now we both appear to be having problem free use of the I-net.
Once you use a Mac, you never go back. Those commercials are pretty accurate.
I'm done with the PC route.
