If you have the money to buy a Mac then go for it, however if you have that kind of money it might be worth having a professional look at your PC.

If you don't have a couple thousand to spend and want a simple budget PC look into the HP Stream Mini - http://www.amazon.com/HP-Stream-200-010-Mini-Desktop/dp/B00R7R1GWK. At $180, it's a brand new full PC that does the basics very well. Windows 10 should be coming out later this year and it will be a free upgrade for Windows 8 users.
