Hi terence,
What a superb blog. I thoroughly read the blog and comments and then went and bought my Elonex 511EB from Waterstones website shop. I must say that I am delighted with the product in terms of capability and price. I have created my own epub book in order to test how easy it was to prepare a text book for the reader. No problems, the Elonex handles epub very well indeed. This is an excellent buy. I now need to find a nice leather case for it and a separate battery charger. I am now seriously planning to put several textbooks of my authorship (Hypnotherapy etc) into epub and offer them in this manner.
To other respondents – keep the comments coming to help with finding cases, books, etc.
