Well, I have followed the Ebay sells very closely, as it's my business after all.
I count 14 units sold(give or take 1 or 2 I may have missed), four of these where my personal extras that I bought to sell, and I know screen text was to small for one user, a few others had an extra unit and saw the prices then decided to sell(or just sold their own, and waiting on batch 2), and of course you have the dislike crowd. I would agree with Ed, the dislikes have been around 6 or 7, and that is a small number out of the overall userbase.
I have many friends who are into the newest and greatest gadgets, and upgrade phones, computers, and sometimes even cars very frequently. If you look on Ebay at any gadgets, handhelds, and the like. You can see many Iphones/ipod, DS, PSP, N900, ect. Devices like these are always past around like baseball cards, someone has gotten tired, another user has just dicovered it, so fourth and so on. This is what makes Ebay great IMO!
So the question of this topic is very misleading, and could be ask of any electronic device on the market. I would never sell my unit, unless it was to get a newer model of the Pandora. It has always been about meeting a demand and need for me, and the Pandora has delivered in spades. The GP2X was awesome, but lacking in many areas, but I only sold mine to get my Pandora. Then I got A Wiz, as I needed something to feel the void while waiting, but it just never really got going in emu's and programs and such, and now we have the Caanoo, and I have my Pandora, so this device is of no interest to me personally.
Many have decided to go with some of the other alternatives on the market, and that doesn't mean there is anything wrong with the Pandora, it just says "Differant strokes, for differant folks"! :lol:
