Also, as JSWolf mentioned, I don't trust a virtual machine not to crash or pause unexpectedly during the update, which may or may not cause problems for the PRS-T1, depending on how Sony have implemented the update. For which reason, even if I were using a Windows PC, I would still rather perform the update by transferring the update file to the PRS-T1 and then initiating the update not connected to a PC. However this is probably just me being paranoid!
