Same here even though I pay the £10 sub each month not really worth the money really in my view as soon as they get rid of the £10 extra sub for the SKY HD the better.My one runs out next month that be the first thing to go.
Fine for me on two windows Vista 32bit pc's no problems at all so far.But the 4gig issue not really been fixed yes it shows up as full 4gig of ram but Vista still only uses the same as before.
I use the Ps3 to download classic games which can be copied to the psp and you can then play them on the psp with no problems.Which is great as the psp is a bit limited on memory.
