The Kindle just came to Canada, and with it came the ability to install a free app available at Amazon.com called "Kindle for PC" on my Canadian Acer. Now I can download Kindle books and read them on my netbook without buying a Kindle gadget. Observations after downloading a couple of "sample" books to test the system but not buying a full book yet (the sample books are handy: the thumbnail includes links to the amazon.com description page and also a direct "Buy" link):
1. Download and setup were simple, all you need is an amazon.com account to register the downloaded app to the same credit card used for buying other merchandise.
2. Navigation is by keyboard button or mouse, and screens are perfectly fitted to the netbook. I was a user of Microsoft's eBook software on my older computers, but found the display too tiny to read on the Acer or when zoomed ruining the page layout. The Kindle app reads extremely well at a standard page layout, although font size can't be modified.
3. I haven't tried sync with other PCs I own, since I don't use them for reading. Supposedly the app will sync and save last location data between "devices" but can't vouch for it.
4. The app does not support the notes and highlights, word search and zoom features that seem to be on the Kindle hardware, but says these are planned "future improvements." It also doesn't make available whatever dictionaries are on the Kindle machine.
5. Unlike the Kindle hardware, the netbook using "Kindle for PC" displays books in color. One of the samples I tried was a Photoshop Elements guide and all its illustrations are in good color, as opposed to greyscale.
All in all, while I'm attracted to the "ebook" idea, I think the combination of a full-featured little netbook PC with an app to read Kindle books is much better than the hardware currently offered by the Kindle. I've read about the Barnes and Noble Nook reader, which seems a step up from the Kindle in hardware and its book catalog, so the jury is out, but I'll probably wait a couple of years for the industry model to mature and settle down before considering another portable device.
