How's the firmware support/availability? For things like graphics tablets, graphics drivers, etc?
I don't think OpenBSD has binary compat with Linux but most Linux software should just need a recompile for BSDs—I'm discouraged from porting given that when it's not a simple recompile I'd have much less idea what to do.
I just cook normal meals and put them in tupperware and take them to work. Doesn't work if you don't have a microwave, but if you don't have a microwave, I'm not sure what you could do other than sandwiches. So whatever you like to eat.
