Hello,
MixVibes on EeePC: I advice you to use an XP version ( EeePC 904HD or EeePC 1000 = 300 - 350€).
The 701 version is cheapiest (=150-200€), but you have to change the OS (Linux) into XP (not really difficult, you can find tutorials on internet)
We tested the 701 version, it works really good with MV 7 + U46MK2.
I think it could be hard to use this version for a live performance (not enough disk space for XP), I advice you to buy the version 904 or 1000 (more powerfull, better stability for live, and 160Go Hard drive

)
I will test the EeePC 1000H with MV7 next week,I will publish a technical review as many people are interested in Netbook.
