I don't know if this offers any additional information to folks more in-the-know about the various reading apps than me (which is most of you), but I received this e-mail from Kobo this morning:
Exciting News!!!
There are lots of new and exciting changes happening in the eReading world, especially with the launch of the new Apple iPad tablet.
Kobo has been working around the clock to develop our FREE iPad app that will launch with the iPad in 60 days - check out a few images of our prototypes below!
Plus, we will have new Tablet apps available for Android & Windows tablets starting in February. We continue to enhance our FREE apps for Blackberry, iPhone, Palm Pre and Android. Kobo is committed to giving you choice when it comes to the devices you read on, the content you read with over 2 million eBooks available, and where you shop with leading retailers adopting Kobo for eReading. Read on the go with your Blackberry, at home on your Tablet - picking up exactly where you left off!
Choose from Kobo's selection of over 2 million eBooks, including $9.99 NY Times bestsellers, and read anytime, anyplace...on any device!
Again, I have no idea if that offers clarification or just more questions.
EDITED TO ADD: Same info is now available on the Kobo website, with images.
