Add 64gb extra storage to your Surface tablet for 60 dollars

Personally I went ahead and pre-ordered the 64 version of the Surface RT tablet. No regrets about that software can be huge these days(especially games). But I wanted to point out that you can buy a class 10 64gb micro SD on ebay for 60 dollars free shipping now-a-days. Class 10 SD cards are as about as fast as they come. Built in SD card support was a huge selling point for me. Is any one else as pleased as i am with the ease of expanding storage on the surface RT?
