Last night I was recording a gig for a client, and it was the first time I'd used a Windows laptop for mobile recording. We'd recorded dozens of podcasts and events with Macs with nary a hitch before that, using otherwise identical hardware and software. Naturally, about an hour and 20 minutes into the recording, everything went haywire for no good reason, and the client lost the final 20 minutes of the program. We'll have to give them a discount on the rate we originally agreed to.
Moral: don't use Windows.
