McAfee and Norton are a waste of money

I'm using Microsoft Security Essentials - It's free, light and no problems thus far

I had a Mac Pro for a year and sold it. Wanted to do a lot of video editing. Software selections were limited, Video cards were limited and EXPENSIVE. There is more user/knowledge support through Windows users for video encoding/editing. I had VMware Fusion with Windows on it and it worked pretty good. Wouldn't run MS Flight Simulator through VMware or Boot Camp nearly as good as the PC. Just didn't find it was worth the money for the limitations I had.

I built my own PC with Windows 7, overclocked the CPU, configured it with the parts I wanted, for much less money and no limitations. Been using it for 6 months, no problems at all. I like Windows 7.

It's not that hard to build a PC. There are lots of tutorial videos for building PC's on You Tube. If you can fly a jet, you can build a PC. Probably the most important aspect of building a PC for a newbie is making sure you get the right components that work well with each other (motherboard to CPU to RAM to power supply) to avoid issues. There's lots of message boards for help. Once you can build your own, with quality components, suited to your needs, for less money, you'll wonder why you didn't do it sooner. Best of all you don't have all the crapware programs that Dell, HP, Acer etc. load up their computers with and slow the thing down.

I have my Mother using an iMac and it's been a good setup for her. Works great for internet and email. For someone with limited knowledge of computers and unable to deal with the slightest glitch, it's a good way to go.
