The machine gets 3.5 out of 5 stars and the reviewer seems to like it a lot. One thing that interested me is that he says that Spring Design is working ewith 40 developers to create or modify apps for the device and a store should be available in June. He also includes a link to a Laptop Blog post on How to find Android Apps for your tablet, ereader or other large screen device.
All in all the review finds the machine a good experience, but questions whether its high price is worth it. The Alex has a $150 premium over the Kindle and the Nook, but, as the reviewer says, that premium buys you a true multitasking device that does both the basics and the extras well.
Competent engineering for sure. Selling and marketing not so much. See http://www.geardiary.com/2010/03/19/alex-readers-price-yo-yos-up-and-down-and-up-again/ for their rather dubious pricing.
