After spending years as an exclusive PC gamer, I decided to get off my high horse and get a PS3. And to this day, I'm glad I did.
It's not one of those things where you have to have one or the other. Hell, most PC screens have more than one input and are able to have a PC and a PS3 connected at the same time, leaving the only hassle left for you to do is stretch over to turn the console on and change the source on your screen. But I digress...
The new slim PS3 is great. Looks great, sounds great, I dare say it tastes great...
Size wise, it's width and length are roughly the same, about the length of an A4 piece of paper. Height is no more than that of the Playstation dualshock controller, so it's not hard to find room for it.
It makes next to no noise, runs fairly cool (as far as this generation of console goes), and isn't a hassle to set up.
I had a little trouble due to my own blinding idiocy, with the fact that I didn't realise you had to set the video and audio outputs every time you change from HDMI to scart. I assumed the video output was faulty, it was just me being a knob.
Little Big Planet 2 is great fun, too. Provides hours of fun with quick and easy to learn controls. If anything, the controls for the game are the perfect way to get used to the Dualshock controller. Stephen Fry's voice acting is great, and despite the simplicity of the platform, it takes a while for the game to bore on you, and not that long after you turn it off, you want to play it again.
Great, sound investment. Plus with the amount of titles out, nowadays, you're always sure to find something you like at a more than reasonable price. :) Brilliant stuff.
