Since I'm just joining this community, I wanted to say hi and introduce myself, and share a little of my first experience with the PE.
I got my pocket eDGe from Woot, so I'm a newcomer to this awesome tab-reader. I got it on Friday, set it up with Ermine, and have been using it for almost everything. I just became the proud owner of my very first house, (my fiancée and I are getting married in 18 days!) and have been using the PE for writing down things we need to furnish and supply it. It's been indispensable for trips to the store, since I can just prop it up in the shopping cart, and cross stuff off as I get it. Also, I've been using it for planning on where to put things, by drawing a map of the floorplan and drawing in the furniture.
I also use it at my job as a math tutor, because it's great for doing algebra on one side, and using the calculator on the other. I've only had it for a few days, so I'm developing new ways to use it in this regard. I will say, that students are way more attentive when I use new technologies in the classroom, which is kind of nice.

Also, I was able to use it with YouVersion to take notes in church on Sunday morning, and I've been converting web-pages to ePubs for dual viewing. It's been wonderful!
Two minor issues I had; of course it is difficult to install apps without market support, (and some apps won't install at all... I expected this.) and I had to subscribe to Ermine on a PC because the website on the PE didn't accept my username and password, even after changing it twice.
I've seen posts floating around that the PE has been discontinued. This makes me quite sad, but it seems to happen a lot with tech I buy. (I bought a Nokia N900, which was dropped like a hot potato less than a year afterward.) I will say with my experience with the N900, when the manufacturer abandons a product, if the community is good, they usually step in and make something awesome. I'm looking forward to see what the Entourage community can do with this awesome device.
Finally, I have some extensive experience with beta testing and Linux, so to all the Devs, I'd be happy and able to play around with things and get back to you with my experiences if you want.
I'm looking forward to getting to know you guys!
