There aren't any major show-stopping issues, but we did get a couple of emails from people who had problems.
You can choose to save on the usb stick itself (there is room on sdb4 for a 300 mb save file, for example), and keep your installation of SP1 on your portable version that way.
PS - If you install Studio 13.37 to your hard drive, you should copy z_extras.sfs to your /root folder. That way the "Load Extras" button on the bar will still work, and you can use the included video and graphics editing software.
