DON'T RUSH is Miss
I know that new
stuff is cool, and double that when it's free, but unless there
is a feature, you need to have, there's no reason to rush into
upgrading to High Sierra.
If your system is critical,
then it might be a good idea to hold back on upgrading. After
all, it's not like High Sierra is a limited resource. If you
don't upgrade today, it'll still be there when you decide you're
ready, complete with patches and and the typical bug-fixes.
To be honest with you, High Sierra is going to really slow down
your computer if it is an older model. Unless there is something
you absolutely need in the new Operating System, I wouldn't upgrade.
You can call me if your aren't sure how old your computer is.
If it is newer, I'd probably give High Sierra a while to mature
before installing it.
Sometimes it is best to slow down to go fast.
