If you can't wait until early 2013 for Surface Pro, there are many Windows 8 slates headed your way with x86 processors such as the Samsung Series 5 Slate, Lenovo IdeaTab Lynx, Acer Iconia W510 and W700. Convertible laptops are also making a comeback with Windows 8 including the Sony Duo 11 Ultrabook,Dell XPS 12, Asus Taichi, and Lenovo IdeaPad Yoga.
Lots of tablets have 3G or 4G LTE connectivity, but the Surface RT is not one of them, although future versions may include this functionality. If you need wireless broadband, you'd be better off looking at the iPad, an Android tablet, or a Windows 8 tablet such as the Samsung Ativ Smart PC.
Type or touch cover
You could use the Surface RT as a standard tablet and spend most of your time in the new so-called modern user interface, ignoring the desktop completely. But if you want to use this tablet to get some serious work done on Excel or Word, then you're going to need a portable keyboard to go along with your new tablet. You can buy two different types of keyboard covers for the Surface: the Touch Cover or the Type Cover. The Touch Cover has flat, pressure sensitive keys and a touchpad, but touch typists will prefer the Type Cover featuring mechanical keys and a multitouch clickpad. The Touch Cover is priced at $120 and the Type Cover costs $130. If you don't mind getting a black Touch Cover, you can save yourself $20 by picking up a $600 Surface RT with 32GB storage and black Touch Cover. Other Touch Cover colors include white, magenta, cyan, or red. Type Cover appears to be black only.
