It's fine, it just doesn't play games that require a hard drive. And that just means FFXI -- which is best played on Xbox 360 or PC to be honest.

I'd say just get it, it's nice and slim and if you know how to take care of your possessions then it will not break and no, mine has never overheated. I doubt they would have released it without a cooling fan knowing it'd overheat and break easily.

Just get it if you want a PS2, the old ones are bulky and loud.
