Are there any cons to use Sublime text 2 portable over Installer version?

I've been using the portable version since it was first offered and have never noticed any issues. The only thing I can think of is that you won't have the "Open with SublimeText..." options when you right click in windows explorer. I use the portable version because I do not have the permissions to install any applications on my work machine (which forces me to become very creative with gaining access to certain applications and resources).

Whenever there is an available portable version for any Software, i choose it. That's the same for Sublime Text 2 and there's no cons (at least that i know) in using the portable version. My version seems pretty fully functional to me.
I'd even say Portable version is way better (specially in case of backing up; only step required to re-install: copy and paste).

Go for it if it's what's tempting you.
