But why couldn't you do this at home though? Don't you have a connection at home? I strongly suggest getting the PS3 permanently connected at home, as the Playstation Network is probably going to be a big part of the PS3s future. Also, there's a good reason to be able to reach the Playstation Store which has lots of neat things for download. And they don't cost much either, Tekken Dark Resurrection costs around £7 and is the most expensive title on there, the only one that costs that much. Then there's the small games made for the PS3 such as Stardust, Gripshift, Blast Factor and such which mostly are around £6 a piece, and PS1 and arcade classics for about £2-3. Then there's the trailers and playable demos of full games that are released from time to time. Word is that a playable demo of Heavenly Sword is coming this week, which is one of the highly anticipated PS3 exclusives.
And there's also the great multiplayer aspect of games like Resistance to consider.
