My mum is about to go overseas and has been persuaded by friends that buying an ereader would be a good thing. I've never met anyone who owns an ereader who didn't find it indispensable, which means of course that eventually I'm going to have to get with the times and buy one myself.
There are loads of models around now, mostly around the $200 price range. I think my mum will end up with a Kindle but it seems to have just too many buttons and functions for my liking. I want an ereader that does what a book does: displays words on a page. The most popular options in Australia are the Sony Reader and the Kobo Wireless, about which I know nothing except that they seem to be very hard to come by. Either unavailable or sold out almost everywhere online that I've looked. (Hello, eBay.) And that both come in pretty colors (as well as more serious tones).
That's it, the sum total of my knowledge. I'm leaning toward the Sony Reader Pocket Edition (oh! but the Kobo has has a quilted back!), while simultaneously trying to imagine my life with bookshelves that no longer need to expand.
