Yeah.. that's kind a why I want to see them through to the end as I hear Sanderson brought the books back up to snuff. I also want to read The Way of Kings eventually as I hear that's amazing, i just hate getting into new series when they start as waiting years between books can really get old.
About the storage space. I had to go with the 8G since they didn't have the bigger ones on stock when I got mine. Birthday gift, so didn't have too much to say. So far I haven't seen the space beeing a problem. Of course it would be nice if you could expand that with SD memory. So far using Dropbox and other cloud services has been enough. What normally would eat my diskspace would be vides, which is not problem if you use Netflix. Just started using the US Netflix myself. Tad better than the UK one. (:
