With most of the world's electronic devices finally standardizing to SD (thank you Sony for finally adopting this standard), it seems most things we own work on either the microSD or regular SD card.  That's why this little package is so handy.  You get both in one neat little package and at 64GB, you'll have plenty of space to store most of your programs, files, etc on your device.The Class 10 rating (ability to move data on/off card at the current maximum speed) is a must for anyone that doesn't want to sit for vital seconds waiting for data to write to the card.  And SanDisk has proven themselves over the years as making a quality product.  Sure, you may occasionally find a dud in their inventory, but they are quick to fix/replace it and that is what matters most.  Buying cheaper cards will land you with a read/write error when you can least afford it.  Don't be the person that loses those important family photos or that document that is due today because of a cheap and defective card.I purchased this particular card for my Asus Transformer, as it fits nicely into the pad itself - and with the optional keyboard attachment (which is capable of holding standard SD cards) it fits there as well.  Making this the perfect solution for my extra memory needs and at a much better bargain than most competitors.  You can certainly purchase more internal memory on your iProduct or Android device (most seem to have 16GB or 32GB variants), but why spend the extra cash for 16GB extra, when you can buy far more in an external card?
