The big difference is that a computer is a computer, and an XBOX/PS3 is a console, made for gaming and entertainment. It's a very hard decision.
A computer is great, you can install programs, access the internet, customize the computer and lots more. There are so many things you can do on the computer. But there are some problems with it. First of all, I do agree with you here. It is true that computers can slow down due to programs, and its easy to be hacked, and not all graphic cards are compatible with every PC game available. Also, on PC's, you don't always have to buy games, you can get free demos online or play games online, but you'll require Adobe Shockwave/Flash Player/Java for most games.
A console, however, is great for gaming. It can entertain you when your bored and more. But it's not much like a computer. You can't really customize it the way you want it, or download programs etc. Also, you won't have to worry about the graphics card, the game won't lag what-so-ever. There is also a less chance of catching a virus on the console, which is great about it. But to use a console, you need a working tv.... and a good one! One more thing, on a console you'll need games to play.
Overall, I recommend everyone should have atleast 1 PC, and a good gaming console (ofcourse, with a tv and a few games). If you have both, you'll be fine and you'll never get bored.
