There's a new iPad competitor in town, with the Microsoft Surface tablet available in two flavours, both made and sold by Microsoft, rather than via third parties sellers.Both have 10.6-inch displays, with the RT 9.3mm thick and the Pro 13.5mm. While the RT weighs 676g, the Pro is a rather heftier 903g. Both come with a magnesium casing, microSD and USB ports and are offered in 32 or 64GB capacities. They also have a rather nice kickstand, useful for watching a movie.That stand is also angled in a way so the webcam (aka the LifeCam) is just right for looking into. it also has Skype-friendly dual microphones, stereo speakers and a cover that doubles up as a keyboard and trackpad, connecting to your tablet magnetically.The difference between the two is down to the inner workings. The RT model runs Windows 8 RT and has an Nvidia ARM chip, while the Pro model runs the standard Windows 8 OS and uses the Intel Core i5 processor. It also has a slightly larger battery capacity. The RT model will be available when Windows 8 launches in October, with the Pro model following in early 2013. No news on price, but it is expected to follow the general pricing of the current tablets on the market.
