I have the Apire one with a 120 GBt hard drive with Linpus and UNR remix dual
boot and find them both fine. Linpus intended for straight forward simple tasks
and does it well. Ubuntu allows full 'command' I have tweaked both as found on
the forums elsewhere. Get lots of fun and delightful to use, boots in seconds.

If you are stuck with the 4GBt flash you can always extend your filing system
with 8GBt additional SD cards or usb stick.
