Not very.  Some packages are masked by the profile so changing profiles 
will change what packages are installed, sometimes.

I'm assuming you are using default-linux/x86/2005.1 and thinking about 
moving to default-linux/x86/2006.0 (there are equivalents for most archs, 
and probably some of the sub-profiles).  If that's the case we see that:

Only in 2005.1: vserver

(I stripped out the context lines, but things aren't wrapping correctly, so 
that my be a little hard to read.)

ANYWAY, looks to me like vserver support is no longer available as a 
sub-profile, probably replaced or superceeded by default-linux/x86/vserver 
and that the default USE flags changed by adding apache2, esd, nptl, udev, 
and xml and removing bitmap-fonts, fortran, oggvorbis, truetype-fonts, 
type1-fonts, and xml2.

nptl and udev you were probably already using, esd maybe not and it'll 
probably bring in a dependency or two.  I betting xml2 has just gone away, 
in favor of xml.  oggvorbis should have also gone away since there's no 
special libraries necessary to handle vorbis data in the ogg wrapper other 
that the ability to handle vorbis data (which can be in another wrapper, 
like matroska) and open ogg wrappers (which can contain other data like 
speex or theora).  Changing the fortran flag will probably make your gcc 
recompile, unless you already had it turned off; I don't actually compile 
fortran, do you?  I'm not really sure what's up with the fonts options, 
but it does make sense to not default to ALL types of fonts.  The biggest 
change is the apache2 flag, so you may want to disable that is you do go 
with 2006.0

Do you mean you want to be able to use binary packages from the server, so 
that you don't have to compile on the notebook?  If so, you probably want 
to keep both make.conf, make.profile, and /etc/portage identical.  (If USE 
flags are different, a binary package will not be used.)
