DuskyRose, you're arguing with strawmen there, not with me. If you wish to carry 30 thousand books directly on your iDevice, by all means do so!

It's just not a practice I would
generally recommend.
I use free Dropbox, and I have 11.4 GB of space there. As you know, there are easy ways to extend your free Dropbox space.
I also have 50 GB of free space in Box.net. And another 50 GB of free space at Copy.com. It's easy for iDevice owners to make use of such promotional offers when they appear.
PS: I trust you know you can easily access your phone's 3G connection on your tablet.
