My touch screen Lenovo Yoga pad
Different strokes for different folks. I personally wouldn't buy anything with the touch screen gimmick unless it was a dedicated tablet.
I listed the reasons I use a Mac. It's a solid build (mine gets tossed around a lot), it's UNIX, which makes it a developers dream with the stuff it comes preinstalled with. Not to mention I went through 3 HP DV1000's (almost $1,800 each at the time) in 2 years before buying my first Mac. And it had nothing to do with downloading software or viruses. They were plastic POS's.
But you're right about one thing. No computer is going to solve your problem if you don't have common sense while browsing the web and downloading shyt.
