Where are the downloads?

Or you could use Opera@USB in combination with something like GoodSync.
+ You can keep your emails and newsfeeds with you in a program - and easier to organise than in the web email software! (Drag and drop, learning filters...)
- Some of the public computers might not allow you to use programs from usb drives, either because they are well-protected, or because the drivers are not up to date (for the oldest computers).

Oh, and SE4 and SE5 both work from USB drives! (you only need to keep with you your serial for SE5)
