Well... I do like to work with multiple monitors and frequently have: 3~5 CAD projects open; 1 Excel spreadsheet; 1 Adobe Document; 1 Outlook mailbox + 1 email open; 1 Word document; 4~6 explorer folders; 1 browser. And alternate heavily between all this. I know I won't be able to do this on a tablet. But if I could open a couple of projects, email, spreadsheet and a browser at the same time I would be happy. I know that if there was enough processing power/memory and a CAD app my n900 could do it.
