Dude... Take a deep breath and consider coming over to the dark side.
Consider this. You can get a 15" MBP with a hi-res non-glare screen. Then max out the RAM with OWC Ram to 16BG. Then put in an OWC Data Doubler as a dedicated scratch disc and your MBP should smoke.
I can't speak to the PC, but like your Lenovo, my Macs "just work". I currently use a 2009 White Macbook with a Seagate Hybrid SSD hard drive and 6GB of Ram. I process HDR and Capture One/P+ files all the time. Is it AWESOME... no, but it's from 2009. And it's made of plastic, and it was $1000 so I don't care about smashing it to bits. I'll be upgrading this year when the new MB's come out and the "old" ones drop a little in price.
I also hate the idea of not having battery swap-ability but you can get "remote batteries" if you're not near a plug for 8 hrs. (http://quickertek.com/products/macbook_air_charger.php) And if your battery loses its ability to hole a charge, it really isn't that hard to change yourself.
As for Apple politics, please enlighten me. I have no idea what you're talking about. Hippies or Facists? Vegetarians or Meat Eaters? Or are you just against their policy of charging a S##tload of money for an awesome machine? Cause it bugs me too.
You know what? I'm an open minded person. I'll look into the option again just like I've done any time I needed a new computer and also in between.
But I have doubts and that's the "politics" I was referring to. And I don't mean politics really - though it somehow appears to be related, but that's where things get really complicated. It's this annoying mother-knows-best approach. Take it or leave it. And once we have sucked you in you'll have to just keep buying and updating because all the other stuff won't really work with it.
But hey, if it's really that good?? After all, my dad has never used any, err, remote assistance for his iPhone - unlike all his other (PC) gadgets that I take care of on a regular basis and from a distance.
I'll keep my eyes open and am curious if Apple will really come out with some kind of retina display. That could be the selling point - unlike their "hi res" 15" display which my 6 year old ThinkPad still beats. And if they maybe then throw in a mouse button or two in addition to the hideous trackpad we might be in business. And for Office (including a fully functional version of PowerPoint and Excel...) I could switch to a Win7 installation. So who knows - maybe I'll give it another shot. Only that this is easily a $3000 endeavor with software and all...
But then again the laptop PC market has nothing better to offer it seems.
I hope I don't sound like a Mac Fanboy, because I've certainly looked at the PC market. But by the time I got done comparing comparable platforms it was all a basically a wash. Plus, like you, I was already heavily invested in the Mac software.
I do love my Macs though, but that's probably because I know how to keep them clean.
BTW - I have heard that Lion sucks.
