They gave today's date, 22 February. A number of sites have added a token amount of commentary to their regurgitations of Spring Design's press releases, but you can also get them
straight from the horse's mouth. The most recent one claims the Alex would be available in their online store ("
Coming soon!") on 22 Feb for $359. Of course, the most recent press release is dated 7 January and I haven't been able to find any more recent mention of the device that wasn't an article mentioning interesting upcoming e-reading devices.
If anyone does have more (recent) information or insight into this, I'd sure be appreciative.
