The surface pro is the only remotely useful tablet they have, but is it outrageously overpriced for the hardware it offers.
The surface RT offers nothing to the user.
very few apps and most of the remotely decent ones, are paid apps where iOS and android have similar or better free alternatives. It has a crappy UI in comparison.
With the surface pro 1 and the recent price drop, it is a much better deal than the ipad as it is actually running a proper desktop OS, but the surface pro 2 is overpriced.
furthermore, for the price of the current surface pro, you can just buy a laptop with a proper keyboard and much better hardware for the same or less money.
Microsoft needs to price the surface pro in a way where it will not be matching the price of laptops with better hardware.
after that, they need to kill off the surface RT (firesale it for $100 and release the source code for the drivers to the cyanogen mod team)
