Are you a specialist or a generalist?

Are you one of those that knows the intimate working of a particular piece of software or hardware? Do you know do things that even the designers didn't anticipate? Odds are you're a specialist.

Do you have a broad knowledge base? Know how to do "lots" of different things with different software, hardware, and operating systems? Chances are your a generalist, or a "Jack of All Trades, Master of None."

What are you thoughts on being one or the other?

I started out as a generalist, then moved into being a specialist with Microsoft System management Server (SMS). Since I've become more of a generalist. I've dabbled in various different things (web development, graphics and video editing with various different pieces of software) yet have not found the time to become really proficient or a master of any of it.

They say...

An expert is someone who knows more and more about less and less,
until they know absolutely everything about nothing.

The sad fact is, most of the time I'm feeling I know absolutely nothing about everything.

So, how have your transitions from one side to the other?
