Late reply but found this thread doing a search for Blink. I have several Blink XT cameras that I got for a great black friday deal.
I totally agree I wouldn't go wireless if I had to do it over again.. too many little sacrifices that have to be made to save batteries. But, it is pretty reliable and app notifications are good. I have an IFTTT setup that arms the system when I leave the house.
Anyway, what I wanted to share was a little project I found on github: GitHub - MattTW/BlinkMonitorProtocol: Unofficial documentation for the Blink Wire-Free HD Home Monitoring & Alert System
It is really intriguing to me.. basically, an app or driver could be written to capture a screenshot from the camera every so often (though if you do it frequently I imagine the battery wouldn't last).
At least I'm considering adding support for it in my Android app (shameless plug - [BETA] Android app for wall mounted tablets). Even if it's not possible to get an up-to-date image in the dashboard it'd be cool if you clicked on the dashboard tile and it could open up the live video stream in a popup window..
