An item reported in August reports on 9 alternatives , another with 7 and android forum turns out to be good place to find out more about the large number of Android tablets now available. I found links there to a comparison of various 'lower end' tablets and a link with release dates.
On the ipad end of the market, the Samsung Galaxy Tab seems to be leading the flock with a comparison between the ipad and the galaxy tab from pcworld, Augen tabs do not seem to have withstood deep scrutiny and no physical sign, as yet of the Asus eee Pad or the MSI windpad and the Blackberry Playpad not as yet launched.
So might be a case of having a good look and to do some hands on play with various models including ones with 7" screens and resistive rather than capacitive screens. If I have time, will also do a read up on the various technical specifications, difference between VIA and rockchip processors plus have a chat with various techy types at mlearn 2010 who will have advice to offer. This will provide a better understanding of capabilities of net tabs and form the basis of next year's 'elearning' project applications.
