Good news, I am holding the A330 in my hands!
We have a test model in the office, expect release for sale soon!
I have played some of the games briefly and it is GOOD.
The build quality is more PSP than Dingoo, I especially like its meaty shoulder buttons and its construction is pleasingly solid.
Sound and video are surprisingly good, you could easily watch movies or TV on it.
You can see a size comparison, it is bigger and sturdier than an old Dingoo that we have, but the screen is also a bit bigger which is a plus. It's more portable and pocket-sized than the PSP, but still feels substantial in your hands.
