Have been using Linux Mint LXDE on a Acer aspire one netbook with a half a gig of RAM, and it has been pleasant. Most of the time am running chromium and firefox with around 10 tabs open amongst them, and the little netbook keeps pushing with out any major slowdowns. It's quite responsive actually.
Lately though have been doing java development on the netbook. Have installed eclipse and the android SDK, eclipse is versatile enough to be usable on the small screen of the netbook with out having a negative effect on the workflow. Of course using the android emulator could be an issue, one which I choose to avoid by just testing on a real android device.
libGDX. libGDX is a cross-platform library that allows you to simultaneously build for the desktop and for Android devices. With libGDX I can be doing little tests while at the desk and then do more in depth tests on the couch or in bed with an android device.
Here is a video of a libGDX demo game
and here is the creator of libGDX showing a demo of the UI library
To get started developing with libGDX watch the video below to see how.
Thanks for reading, and look forward to more details about libGDX as I get more into it and a detailed post about another java game engine called JMonkey.
