You mastered Photoshop quicker than you did iTunes? That would make you either a Photoshop genius or an iTunes retard.
I've been a Photoshop retoucher/illustrator in the entertainment industry for over 10 years and I'd say I'm far from mastering my craft or Photoshop. Photoshop is the only reason I can even participate in this hobby and afford to buy these fancy schmancy tube dealies or gi-mongous wooden speaker whatchamahoochies.
On average I'm pushing pixels via Photoshop 50-80 hours a week for mom and pop shops like CBS/Paramount and Sony, and I still learn something new every time I perform a digital boob job, a binary face lift or when I turn a lo-rez spread ad into hi-rez finished art so a printer can make sure whats-her-name's mug'n butt will appear all young and fresh when it's committed to the ol' Gutenberg.
That damn CS2 humbles me every day. I can't wait for CS3. With iTunes I just care about managing tunes and getting songs on that little white and silver gizmo so I can listen to them while I'm running on my hamster treadmill.
Yeah, I'd definitely say I'm losing the battle for mastery of the digital arts. So does that make me a nano moron? Maybe. But, I can live with that, heheh.
