I had many of them.
I had an archos 404 in mid 2000's and I was able to run small linux apps on it , I had handheld devices based on windows mobile , I had the smallest laptops , the first android phone and the first tablet .
The last device I bet on wa the Pocket Chip , but recently NextThingCo did hit the bucket and I sold it on ebay.
None of this device was the one I wanted , DP5 is the desperate try to have the one device I will bring with me every day , the one that always pay itself .
Enjoy this project?
