I agree a huge step up from iPad 1 but not that much from the iPad 2. The voice to text would be interesting but not something I would use. BTW I purchased my husband a kindle touch a few weeks ago and it has a txt to voice function, he can now have a book read to him while folding the washing - brilliant idea.
I have the latest kindle before the touch and have not felt the need to update even tho I am a "tech head" (kids description of me, not mine). I am going to wait for the next model at least before updating.
We have the kindle and kindle touch and love them both.When looking on Amazon unless you are going to use a forwarder or have someone in the US who can forward your purchases for you make sure you are looking at the international shipping page as not all models are available in all countries. The Kindle touch I got for my husband has advertisements which show up on the front screen, and because of this they are $30 less than the regular kindle but it's only available for purchase in the US. As Gert says there are quite a few models available so you really need to do your research. If you are in Australia some of the models are now available through Big W, Dick Smith and Woolworths - I found the staff in these stores have no idea about the product but you can at least get a feel of a few of the models before purchasing.In the past I've used iPads, iPods and other ereaders but have found my kindle far superior.
