I know this is a dumb question but how would an external storage exactly work with Kobo? I'm very new to e-readers. I was browsing through a bookstore a few months back and saw Kobo readers on their shelf. And just this past week, I decided to buy a Glo. And my gaddd, I haven't put it down since. I even bought the sleep cover. Anyway, I'm thinking of buying a micro sd. But is it really worth it? I'm willing to dish out some money for a SanDisk class 10 32gb one. But will I really need all that space? I was thinking of just getting maybe an 8 or 16gb one, but why not go for broke? Also, does it really have to be class 10? They are hella expensive. I've read some posts here where loading books from SD takes longer to load. If I can't afford a class 10 one, will a class 4 work just as well, or will there be some noticeable performance change? And will it work the same way as the internal storage does? I'm also using Calibre to push books (I really like to download fics over the net and edit the heck out of their metadata to make them look legit) to my Glo. Will I have the option to push it to internal or external storage?

I know those are a lot of questions, but I really hope you guys can answer them. Thanks!
