If you thought 1GB of memory was ample for the average personal computer, you can forget it. Now 2GB is the minimum that users should be aiming at. At least according to Dell chief executive, Kevin Rollins, who told delegates at a conference in Shanghai on Friday: "I think they tell you maybe 1 gig [gigabyte] of memory is okay. No. Two gigs of memory would be great." At least that is accordinf to iTnews in Australia.
