And I'll always remember these things about Windows vs Linux: * My Behringer UCA-202 class-compliant USB sound card works out of the box with Linux. It requires installing a driver on Windows XP.
* My band used to use a Presonus 12-channel Firewire device to record our church services, until our sound tech's laptop died and he got one with Windows 7 on it. The drivers don't work on Windows 7.
