It depends what you want, Em_Scape.

The tablet has plenty of apps, even if the enTourage store closes you can get them from the Amazon app store and several others. If you want guaranteed support, don't buy. If you want a dualbook that works well, seems sturdy, and has a very nice (IMHO) e-ink reader on one side and a solid (though not necessarily spectacular) Android tablet on the other -- well, I don't think you'll find that combo anywhere else.
Even if the company fails tomorrow (and we don't know that it will, this could be a problem with some of their servers) I am glad I bought my Pocket eDGe in February. I like it so much I have paid for a full-sized eDGe from an ebay seller. Now if it would only arrive!!
