Laptop Comparison Help

Currently I have a Dell Studio Laptop that has a Intel® Core™2 Duo Processor T9550 (6M Cache, 2.66 GHz, 1066 MHz FSB), has 4gbs of ram, an ati mobility radeon hd 4500 graphics card, and a good sound blaster sound card. It also has 1080p display with a backlit keyboard. Basically got it loaded when ever I bought it awhile back. My question is would getting a surface pro whenever it comes out or another one of the new laptops to be released be that much of an upgrade besides having touch input (Currently running release preview, and it runs amazingly)? Thanks for the help!
