Hello,

1. yes it can play flash9 in the browser itself. Also there are many third party apps llike mtube which mostly work lilke the youtube app in iphone only that you can also save the flash videos and watch them later offline. There is also the upcoming canola
plugin which does the same thing with a much better interface.

2.Yeah the functionality is very good and it can replace your normal phone if you have wifi around.

3.Not yet but there is abhiword which is under development since a while.

4. The hand writing editor is not the best but in fact i havent seen anything like that in any other portable device.

5. No ethernet port but it hsa a mini usb whic works well with OTG.
