To be honest - as a relatively new Ubuntu user - and an occasional OSX user - trying to get stuff done on the mac is beginning to annoy me more and more.

Apple make some fantastic software - the iLife suite is pretty awesome. That might be reason enough to buy one - (and the hardware design is typically good as well). But just looking at the OS - and what I use the system for on a day to day basis - and Apple's advantage in the OS space is a lot less than it used to be. (And snow leopard doesn't look like changing that from an end user perspective)

rythie said,

"Apple's emerging threat is Linux/Open Source, because " [reasons]

to which you (mikecuesta)replied

"I don't think for a second that Linux/Open Source is an emerging threat to OS X, " with no rationale or logic to support that viewpoint.

"I don't think X", without supporting reasons is an almost meaningless response in a discussion. I am surprised it got so many upvotes. Just imagine someone responded to you with "Oh yeah? I do think so" without providing any rationale.

Your response could validate rythie's "classical innovator's dilemma" argument, since in a classic innovator's dilemma the proponents of the disrupted product never "think for a second" that the disrupting product is "an emerging threat" till it is too late.
