I'm looking to buy a new laptop, but as most of them come with Windows 8, I'm concerned about running the ETB Digitools, for my Digidash. Has anyone else tried it?

it should work on anything. even a mac. It certainly works on Windows 7.

I think you only real concern is the USB to serial cable driver. I did have issues with windows 7 when I first got it and one of the cables I bought would work due to the chip set/driver
