A friend of ours had one with her when we were in Malta at the end of February.
She finished a book she was reading so went and logged on to buy another plus was using it for emails and Skype.
I have a Kindle and find it's excellent, particularly because of the battery life. It lasts me up to 2 months with no problem if I'm not logged onto the WiFi. However, when we travel I also take my Dell mini 10 as I find it's better for other internet access. If you just want a reader with a fantastic anti-glare screen then I would highly recommend the Kindle.
If you want it to do other stuff, then may be worth looking at one of the other androids.
