1. What is the intended goal of the OP?
2. How much time was spent in development?
3. What has been the feedback from potential buyers?
4. Discuss the development community and their involvement in future expansions.
5. When will it hit retail?
These are my personal opinions, and since I only first heard about the OP project about one year ago, I don't know if I should even try to answer them.
1. To create an open handheld device that can be used both as a handheld game console AND as a mini-laptop, with no "chains" limiting what you can do with it.
2. (not for me to answer, but I guess longer than originally planned, and amazing that the OPT actually succeeded)
3. Depending on who I show it to, reactions range from "Wow, that is a TINY laptop" and "What linux distro are you running?" to "Can you make phone calls with it?" and "My smartphone is more powerful". About the price: some people consider it to be expensive ("my phone is cheaper, looks nicer and can do more"), others consider it to be relatively cheap ("my laptop is more expensive, has worse battery life and is harder to carry around").
4. Given the size of the Pandora community (~5000 Pandora owners), the dev community is relatively huge (probably ~100 devs). There are >700 PNDs on the repo at the moment, many of them are high-quality software. The Pandora attracts devs from many other communities: of course Free Software / Open Source enthusiasts, but also people who like to make homebrew stuff on other hardware but get tired of how they have to fight against chains created by companies like Sony, indie game devs, people who are new to programming and veterans with 30 or more years of experience in hobby coding, people who are new to GNU/Linux and die-hard GNU/Linux experts, assembly hackers and Python programmers, etc. So unlike many commercial game consoles, there will never be something like "the final game" for the Pandora, and nothing new will ever come out after that one. There will always be more to come, just like there are still people doing new stuff (in 2012!) for, say, the Commodore 64. That's the advantage of an open platform with a nice dev ecosystem. Moreover, the Pandora is the first and at this moment still the
ONLY handheld device for which it is possible to code
on the device itself, without needing any auxiliary hardware. In my opinion, this is what makes it so very unique.
5. It has already.
