As someone who's been following the price of this TV on Amazon for a while, I can say this isn't a very rare or special price. It's been at $300 mark at least several times over the course of the year.
There's a large thread about it here:

From http://9to5mac.files.wordpress.com/2014/02/tablet-battery-life.jpg, it shows 614 minutes of wifi browsing and 604 minutes of video. That's 10+ hours.
Very intensive games will probably be between 7-10 hours, but that's still long enough to consider "infinite" by my standards. In other...
It's a Retina mini, so 2048x1536.
That's 10+ hours of non stop heavy use, like watching a video over wifi or playing 3D games.
On a typical day I don't spend 10 hours on it, so it lasts a lot longer. For example, it's 1:28 AM and I haven't charged it since last morning, and it's at 77%...

I was able to get it to display the colors absolutely smoothly when I tried with resolutions of 1440x900 or lower in Windows.
However, I still can't get it to work properly at 3840x2160 at all.
I've tried the Accell active mDP->HDMI adapter, but...
Ok, I've gotten to the bottom of the issue.

Yeah, it's the same problem as alamone described.

I've tried both the latest firmware for 39" and 50", no...
Yep, that's me. :)
Thanks, I just found out how to access the service menu (MENU, 0, 0, 0, 0), and the version info is there. Next up I lowered the backlight brightness, so it's much easier to look from up close now. I've already set sharpness to 0 (made a big improvement), and turned noise...
