In reference to the Long boot times:

I think this is syptomatic of any PC based workstation as the operating system must load, Vst's must load, etc. etc.

One work around for this is to purchase an Un-interruptible power supply for Live situations. So if some bonehead yanks the power from your keyboard rig, you do not have to re-boot.

I think the Neko has a UPS built internally to address this issue.

I always use one when I play for both the keyboards and the Powered mixer. My powered mixer is especially sensitive to low voltage, so the power conditioner helps maintain constant voltage and protects my equipment.
