Limit vs. No Limit?

Greetings.

I've been playing limit play money games for a few months now. I've also been reading the various books on Limit (WLLH, SSH, ect.).

Then I read this where the second poster recommended against Limit because he felt NL was easier to learn, had less variance and because there would be an UNlearning curve when you made the move from limit to, in his words, "real poker."

Now, leaving the "real poker" comment aside, is there any data from respectable sources on the variance of limit vs. NL?

I'd also like comments regarding ease of learning, but frankly I find poker theory easy (it's the aplication that's hard [img]/images/graemlins/wink.gif[/img])
