A similar question to this one was asked a few weeks ago, so you may get some ideas from the answer I wrote, which you can find here. The answer also includes links to an article on the plus and minus points of the new Surface tablet.
Now that the tablet is on sale, you can also find out how new users feel about it: If you type 'microsoft surfact tablet' in a search engine plus the word 'review' you will find plenty of opinions. Generally, there is a lot praise for the kickstand and the detachable keyboard, and most users find the tablet good to handle and strongly made. The USB port and extra storage space are also commended. However, it's felt that the device should be compatible with more software, and it is not considered ideal for business users. Overall it's considered a good product, but one with a lot of flaws for the price.
