I'm still new to the Mac world but I used to install Office on my old, drive-less PC all the time. Would I be able to do the same and copy iWork and/or Office 2008 from disc to a USB HD drive (Western Digital)? I have access to a Mac w/drive for awhile but, once my new Air arrives, I won't (so no remote disc option for me). These are the only 2 programs I will ever need to install (from disc) so I'd prefer not to buy the portable super drive. Thanks.
