My brother has PC that should be able to run this game, and I have PC that can't, but I do have a PS3. I've been bitching at my brother for ages to get a PS3 so we can do more Co-op. Now we can do Portal 2 co-op. There was no way I was going to get Portal 2 until I realised I'd be able to play cross platform co-op with my brother. Now a purchase is likely, or rather 2 purchases are likely. Though not quite sure when.
