I am not exactly sure that is entirely true. If the Playbook or Galaxy Tab 7" were priced comparably, I probably would've gone for one of them. For me, it was the size and price that were the sellers. I liked what Kobo had to offer in the Vox, but if I could get the camera and 3G included, that would be worth a little more money...
I believe Pulse is supposed to be available to anyone who has downloaded the Kobo app - not sure when that will be. Hopefully soon, because the Pulse is very low at the moment (pun intended!!!). I am discussing my books with...myself! At least for the books I am reading (and some are popular!).
