Other advantages:

- tempfile ships with every ruby install
- tempfiles are guaranteed to be removed on process termination
- if you are going to need it anyway, you can as well create it
directly, remember, you can control the point in time when the
tempfile instance is created and thus when the file will be created
- tempfile is for "free" while you'll have to maintain every homegrown solution
