Wanted to get some advice on what Tablet PC to buy for a small business. We are an Real Estate apprasil and real investing business. We plan to use the Tablet to run the appraisil software ( which requires 1GB of ram, and 800 MHZ proc ). We will also be running a few open Excel spreadsheets. I would prefer XP based OS. Would also like Touchscreen function ( not a deal breaker though ). I have looked at the Dell Latitude Series, and as I configured it the price soared to over 3700 dollars. Any ideas on what brand and where to buy a good Tablet PC plz ?
