Once again I spent the day using Mepis 8 on the 4GB pendrive on my EeePC 901. Quite honestly, it lacks very little for normal day-2-day use although it might just be very marginally slower. More here
Additionally, it seems, for reasons I haven’t investigated, to run into high CPU problems with windows graying out momentarily and the whole screen freezing.
I managed to get Yakuake working fine today simply by changing the action key from F12 to F10.
