   This HP Laptop is getting a bit long in the tooth (2007 vintage, I   
   think) ... so recently I went on a Shopping Spree and brought myself a   
   brand new Desktop for about $700   
      
   It hasn't made it out of the box yet .... I'm soooo used to using this   
   Laptop on a little T.V. Dinner-type table with the T.V. over the top of   
   the screen.   
      
   Having to convert to a Desktop Computer just seems to be too much trouble!!
