Since adobe is pulling back on that you find tablets a revision behind and folk are gripping about that plus issues like Hulu.com and other sites do not play. Is this OK with you? That is, you are not expecting a PC level experience are you?

About updates. If there is a harsh lesson to learn, NEVER get a tablet with a promise that the OS will be upgraded. Of course you have folk that live on promises.

I've been looking to purchase a tablet for a while now and I could use some suggestions.
Now here's what I'm looking for:
-10 inch Screen
-USB 2.0 or 3.0 port
-Full HDMI port
-Flash support
-Android OS (Jelly Bean) if possible
-Decent battery life
-Fully Memory Card Slot
-Dual core processor
-At Least 1GB of ram
-Full HD Screen (1920X1080p)
-16GB Hard Drive Space (I have a 500GB portable HDD, so storage won't be an issue).
My main use for this tablet would be personal just something I can pick up when I don't feel like turning on my laptop. I'll mainly have it connected to my 40 inch Samsung. I've been looking at the Toshiba Thrive, but I don't know if it will get the 4.1 OS update? So I don't know if I should buy one now or just wait a while until newer ones are released? Thank you for your opinions in advance.
