Leo
He seems to be the only main host on TechTV that gives the mac props. They do have a few other support staff people that seem to be keen on Macs. That Megan girl on SS comes to mind and there is another guy (kinda skinny, taller, with blondish hair--Not very helpful, I know) who is a huge Mac supporter. He always brings up the Mac in comparisons and things. Problem is he sees the camera once in a blue moon.
But Leo does a pretty good job. He covers the Mac at what I consider to be a socially acceptable level. Any more and he'd hear screams of protest, any less and he'd...well...hear screams of protest, except from a smaller percentage of the population. And since OS X came out nearly everything he says about the Mac is positive. I remember him showing off his iBook in a review of another product for seemingly no reason other than he was proud of it. That was pretty positive.
John Dvorak on Silicon Spin is an ass. I often like the subjects he has on his show, but I rarely agree with his viewpoints or methods of expressing them. In general, but especially in regards to Apple. He is most definitely anti-Apple. He has predicted their death and the failure of most Mac products and considers just about all things Apple sub-par on quality. He has poo-poo-ed iPhoto, the iPod, Job's keynotes...everything.
I really don't care for him. Blah. I think we need a gagging emoticon. Maybe one with a finger down its throat or something...
