Query: Good start but way more to go.

The Kindle is streamlined for buying content from Amazon. If you already have a collection of items in PDF/Word etc you want to read on this device - forget about it.Also, I would like to have a little folding stand at the back of the unit so I can put it on the table and not hold it all the time.For a $299 device - couldn't amazon include a bag?And if you want your content sent to your kindle - .12 cents a megabyte...Its a good start but I think with some competition this device will get to the right cost and right specs.
