This is what I use. I probably don't need 16gigs nor do I need a class 10 for a piddley Nook, but it was sickeningly cheap. That place also has brick and mortar stores in Rockville and Fairfax.

you want to get a class 6 speed. class 10 speed is a gimic... they are subjectively rated to the class 10 speed. 6 is fast enough for good memory saving of the games.

I gt a cheaper one a while go so she could save/print her phone pics. We use it for the tablet too.

I need to get one of these for my sons tablet. (he mainly plays games on it if it matters)

Does brand matter or is a memory card a memory card...

there seems to be a huge range of prices
