Too much good things had been said about Novo7A, here's my negative thoughts so far.
1. Very weak or no wifi signal after 5m away from router.
2. Market (1.7B or 1.7.2) is not 100% working with some apps missing. (New tablet/processor needs time)
3. Go widgets gives error (Problem Loading Widget) after reboot.
4. Side panel touch screen/button aren't as responsive.
5. Apps compatibility still aren't good enough. (New tablet/processor needs time)
6. On 1.6T/1.7B/1.7.2 seems to have 0.1-0.3s lag when I cut multiple fruits on fruit ninja. (could be a software thingy)
7. Soft speaker and volume+ app doesn't help (much).
8. Skype video not working.
Picking bones.
9. Would be good if there're GPS & bluetooth

10. View angle & screen could be better.
11. Cameras could have been better, especially if there's LED flash

12. Firmware update could be faster, Onda already released their official 1.6.2 some days back. I guess Ainol just want to released 1.7.x
