Sorry I wasn't suggesting that you couldn't afford it. Anyone who can afford a Microsoft Surface can obviously afford to buy microSD card. I just got burned buying off
EBay and I wouldn't want anyone else to go through the same thing as I did. I agree with you... the 128gb price point is not worth it at this current point. Just get a 64gb for cheaper until 128gb price drops. Since you are in Canada keep on the look out for NCIX/Future Shop or Canada Computers. BTW...NCIX does sell the 128gb card here in Canada:

Your last point I do not agree with. There is obviously a fabrication difference between 64gb and 128gb--the flash memory is much smaller in the 128gb. If there wasn't a difference, then all microSD manufacturers would offer 128gb size. As other posters have commented currently only Kingston and SanDisk offer 128gb for a reason.
