There are a number of netbook/laptop specials about these days, which with 12" or smaller screen are ideal for travelling purposes.  Most seem to have a 32GB 'hard drive' (essentially eMMC devices).

However, once home the upgrades will start, including the Anniversary update, meaning there is not enough room on the drive to run the install let alone have it work afterwards.

Has anyone completed such upgrades/updates on these spec machines?
