While I have heaped praises, here comes the fine print. Windows 8 has inherently built two views the Metro mode and the Desktop mode. The Metro mode which is the tablet interface with the tiled views is a distinctly different environment from the more classic Windows Desktop. So applications that were developed for your Windows PC will function in your desktop mode as against your Metro or tablet mode, and they don't seamlessly transition when you switch modes. So you do get the power of the desktop in your tablet but only in your good old Desktop world. For applications to run effectively in a tablet environment you will have to depend on the Microsoft app store, which I would hazard a guess is still in its fledgeling state. Further the keyboard which looked like an ultra cool add-on, is a necessity in the Windows 8 world.
So yes you can own one single device, but you don't eliminate the Desktop PC. You do make a big save by not having to buy a separate Ultrabook, but in Surface you actually have a cool-compact Ultrabook with tablet functionality. While you do get to use your existing desktop apps, you don't get to use them with the tablet interface, so back to shopping in the app store. Finally not sure everyone would enjoy working on a 10.4 inch Windows Ultrabook as against the 13 inch or larger variety. For e.g a creative designer will any day like to use the larger screen in their laptops rather than hunching over a tablet.
While Surface is far from perfect, to their credit Microsoft has taken us one step closer to bidding goodbye to the PCs. By virtue of having come out with a powerful product, they will keep Apple and other tablet manufacturers on their toes. Surface will certainly force manufacturers back to the drawing boards to solve the rather challenging problem of merging the longstanding PCs and revolutionary Tablets. While we all eagerly await the next wave of Tablets, it will still be a while before we say "RIP PC".
