re-purposing old fone as media center pc
 

i have on occasion used my old galaxy s-2 as a home theater media hub. many fones support mhl (media hdmi link) and the cables are cheap online (e.g.: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1 ).

once you get your fones picture on your large screen tv, the next step is to install the software to manage your media. xbmc makes an app for android which can be downloaded here: http://xbmc.org/download/

once installed you can use another android device and install the xbmc remote app to control your media server (which is the fone connected to your tv). i would assume that a blu-tooth remote would also work.

other benefits are streaming videos from another fone or tablet should also work once dlna is enabled. xbmc addons (such as youtube, hulu, channel-1) work the same as if they were running on linux, windows, mac. you can launch other android apps from within xbmc although they cant be controlled with the remote.

the limitation is that my fone is limited to a 720p resolution (ymmv).
