I hate my HP Laptop, but should I get a MAC?

This is the exact one I own.

At the beginning of college I bought a HP laptop for around 1400 with only a year of warranty. A year and a month passed and my laptop started showing me 6 split windows with 6 cursors. I waited for about four months to get my laptop back in perfect condition. I was told that I shouldn’t use my laptop for more than two hours because it will overheat. I find this unrealistic. Maybe in the year 2003 I would have been okay with only two hours of computer use but in these days, there’s no way. But the laptop does turn itself off after overheating, so I wait an hour before turning it back on. After this I got four Trojan Viruses, the last one wouldn’t allow me to turn on my laptop. I got Windows 7 reinstalled and ran virus scans and it was gone. A few months more later my HP laptop will not even start properly. It’ll show me 6 split screens again with gibberish written all over it, and then a black screen.

It’s time I got a new computer. But the whole time I got the viruses I thought, I should get a MAC. This time I’d like the desktop version; iMAC. I also really love the programs available for MACs.

Am I making the right decision? I really hope I am. All I know is that I’m never purchasing HP again.
