That's been my experience: unless you use raw bytes a lot, I find that
porting apps from 2 to 3 isn't difficult at all. You sometimes have
to tweak text I/O stuff a little to fix encoding issues.
Porting apps that use bytes is more work, but if you're abandoning 2.x
support, usually not too bad.
The real headache is trying to keep a "byte-centric" application
backwards compatible so that it will run under 2.x or 3.x. I used to
try to keep things backwards compatible, but have recently started to
abandon 2.x support in my (mostly internal) apps.
