I've had my AA1 ( linpus) for a few months, and am now passing it on - upgrading! Obviously I need to restore it to the "out of the box" condition. I've got the recovery disk, but am nervous, after reading some of the posts, about making a recovery USB stick (I have another computer with a DVD drive) and about using it. Is it really simple? Do I just put in the disk and a USB stick, put the contents of the disk on the stick and then put it in the Acer and boot it up? Will it crash both the computers? Please can someone tell me step by step how to do it simply, easily and reliably!
