I popped into ASDA last night & saw this advertised but couldn't get a good look & can not find anything on the web.
This deal was for an Acer 5720 Laptop with 2gb ram, 160gb hard drive (120gb poss), 15" screen, core duo processor (not sure spec).
I'm posting this as it seems like a very very good deal & someone may be able to get the full spec. Sorry I don't have further information but thought even with this limited information it was worth a post.
It is 160gb, but dual core not core duo
