Hi, looking for some advice from owners who may have experience with both the Kobo Wifi and other devices. I'm looking to pick up another ereader (I have both a Nook Wifi + 3G and a Nook Color and my girlfriend has an original Kindle) am wondering about the Kobo. Someone on my local Craigslist is selling a new-in-box one for $70 and I'm tempted to grab it, but if I'm not mistaken the Kobo can only handle two types of file formats. I'm hoping that's not true but I might be willing to deal with the inconvenience should it be a solid device. Thanks for any tips.
