Not really, unless you can transfer the update file direct to the card in your camera. That doesn't work for me with the X100. My card reader died but the MBP reader works.
My computer refuses to transfer the .dat file onto the X100's card when I plug it in. I did update the camera to 1.10 on the same computer though. And I didn't have a card reader back then either. Completely forgot how I managed that. Thanks for your reply.
