The PS3 really does do everything. It just got Hulu Plus in the US recently, and now the console has just started streaming movies action in the UK, with Lovefilm. If you are in the UK, it is free. You just have to have a £5.99 or above monthly Lovefilm subscription.
Just be aware that there’s a limit on how much streaming you can do at that price point. Those restrictions go away on the £9.99 top tier, letting you enjoy as many movies as you want.
