I would think that as long as you back up personal and important files you 
could do it as often as needed to maintsin security and stability.  You may 
want to use --pretend (-p) to see exactly what would be done and also use 
regular updates instead of deep updates which should only be used when needed.

I don't see a single problem with that.  Compiles may indeed be a bit slow but 
it will get done.  And if you must compile on another machine look into 
chroots. Another option is Sabayon. I know this is a Gentoo mailing list but 
Sabayon is a derivative of Gentoo but with Entropy (it's package manager) it 
doesn't have to compile and it even offers a GUI (though I don't use it much) 
but it does keep portage and emerge can still be used.  A CoreCD may be just 
what you need (or a Gentoo chroot on a desktop and then transfer it to your 
laptop).

I personally run a Gentoo system after having Sabayon 4.2 and I obviously 
stuck with Gentoo so...
