Hi Elliot- By 'streaming' I'm assuming you mean playing flash video files. The Nexus 7 has the latest Android operating system, known by the code name 'Jelly Bean'. Adobe, the maker of Flash is not supporting ANY mobile device on either Android or Apple's iOS from here on out so any 'new' tablet you buy that is running the latest version of the Android operating system...Jelly Bean...will not support Flash out of the box. The reason that Adobe has decided to stop support for any future mobile device is because the entire web is moving towards the HTML5 protocol which in fact includes its own video streaming ability and which the Nexus 7 supports.
However...there is a workaround to run Flash on the Nexus 7...so no reason to be disappointed! If you'd used the 'search' function on the forum (which I recommend you do for any questions before you post) you'd see we actually have several threads on this forum that show you how to enable 'Flash' on the Nexus 7 by installing the Flash APK onto the device manually and using an alternative browser instead of the built-in 'Chrome' browser.
Now the 'Chrome' browser on the Nexus 7 is widely regarded as the absolute BEST mobile browser that exists and it fully supports the most modern HTML5 specs. Websites like 'Youtube' work with it as do many other sites however as I explained above not 'Flash' because Adobe won't support it. This has nothing to do with Google really.
Anyway, here's a link to find out more information on running 'Flash' on your Nexus 7:

I use it all the time for that. You just have to know how to do it depending on the site.
Hope this helps.
