AS is lack of hardware support.
Lack of over-clocking.
Lack of alternative suppliers with advanced features.
Lack of software. Yes, the ONE program for doing task X will be good, but lack of choice measn you can't find the BEST for each individual.
Lack of support for 'new' connectivity.
BUT, you gotta hand it to them , WHEN Apple bring a new machien it is ALWYAS the fastes/latest technology. The only real problem they hae is 6 months later it's surpassed and Apple take too long to bring otu a new model

The latest gen G5 is a SCREAMER for high memory applications ( 8Gb RAM at 1.25G access - but still only 400MHz ram !!

) BUT so-so on ordinary office applicatiosn, browsing etc.
I'd take a MAC for posing and a PC for tweaking
