As to response number 1, really? Look at the Apps available on the iPad that aren't available or supported on the other iOS devices. Just in the area of Document creation/editing and presentation alone, make the iPad a viable alternative to a laptop for many people, including myself. The iPod Touch or iPhone simply cannot fill that bill. It is a simple fact that the iPad is cannibalizing laptop and net-book sales (for Apple and others). The iPod Touch did not. Therefore, your first statement is incorrect. Just because you may not use it for more than you would use an iPod Touch, is not a reflection of the views of the other 14.8 million users or the capabilities of the device.
I have a friend who uses his microwave that sits on his counter for nothing more than a place to store his bread. His failure to use or recognize additional capabilities of his microwave does not mean that a microwave is nothing more than a large breadbox.
As to statement number 2: Really? You have completely discredited yourself. Especially with the absoluteness of the statement, "Nobody". By April, Apple had already sold 600,000 books. The Kindle Reader has been as high as number 5 on the top downloads, and is today number 100 on a massive list of Apps for the iPad. I can assure you, people aren't downloading it to "store their bread".
The Kindle Reader is an excellent reader for the record, and I can see why people like it. It's praise is fully deserved. However, the Kindle as a web browser? It's "experimental" as stated by Amazon, and it is pretty useless. Media? Pictures? The list is long as to what a Kindle does not do, and what "Nobody" actually does on it.
So you can get a device that is a decent or good reader, and a great almost everything else, or you can get a great reader that does almost nothing else. I, personally, like to take ONE device on the road with me thank you.
IMO, amazon should keep that minimal as can be.
No need to experiment, the screen is specialized, and specialized well.
Definitely a place for it that isn't going to be met by the media tablet sector.
