Hi all, I posted these questions to Sony's web site and also looked for answers there, but had no success. If anyone could just answer these questions, I would be much obliged! Not trying to start a flame war, I just want to know these simple answers! Thanks, Ashish 1. Is there any difference between the 80gb model and 160gb model other than hard drive space? 2. Is there an actual internet browser (like Firefox or Opera) for the PS3, or can I only connect to Sony specific sites (like xbox live)? 3. Are there any models of the PS3 which are still for sale and are backwards compatible with PS2?
