Nikkie- Are you using ADE's from Overdrive, or purchasing? And how do you get the books onto the iPhone? The MR threads I've read about txtr indicated there were issues with having to have a German ADE account...
BOb- (I've always wondered - are you the same pilotbob from various Palm forums years ago?) Amazon's selection doesn't appear to be a problem, but I was still under the impression the Kindle format was uncrackable. I rarely buy more than 4-5 books at a time and read them before I buy more. I managed a Waldenbooks during grad school and amassed a scary TBR pile thanks to employee discounts and ARCs. Moving that collection 3 times taught me a few lessons.
Tracking and backing up eBooks can be just as laborious. Although, I was in the best shape of my life when I ran that store.
