Yes, that's what I meant - depends on your miner - whether you can generate enough bitcoins to be able to recover your costs. The Nexus 2012 version has gone down in price, so it might be worth it - depending on your ROI goals.

I did notice that EasyMiner eventually hangs - the display no longer updates and the Nexus wants to stop the app when I try to interact with it. The miner continues to run and continues to process pool shares as shown on the pool stats page.

For a test I want to try switching over to cgminer on the Nexus 7 (uses bfgminer by default). There's a place in the settings where you can enter your cgminer command line parameters; I think there's a file you can use to configure it, but I can't seem to find out about it's format or name. Using cgminer might have an effect on Easy Miner's hangs - who knows though!

I also tried hooking up a Raspberry Pi computer - works great! Takes a little learning - not much more than needed to get this running and seems to be very stable (during the past 24h, so no long term experience yet).

If you want to go with Raspberry Pi, you'll need a few things:

* Raspberry Pi model B
* Powered USB hub
* Some way to go wireless - you can get ethernet to wifi dongles or use a router as a client bridge
* SD Card compatible with the Raspberry Pi
* Operating system and miner software to run the miner
