I can see the branding, but they really need developing. The only buyers you are likely to find in the domain market will themselves be developers, and as such will lowball you terribly. Whereas an info site, app directory, or even a tool to help optimise downloaded apps to preserve resources (or even an online guide of tips on apps) would make the domain name very relevant to the content, probably cost substantially less than $1,000 to put up, and then be worth some real money once it started getting traffic/rev.
That "light" suffix, by the way, makes perfect sense to me -- I actually used to run a site that had "lite" in its name, and ended up registering the "light" version when I kept seeing people coming in off of search engines looking for the name of the site but with "light" instead of "lite" in it.
