I have no idea how this went from objective views of the what laptop offers the best specs with the best price, into a personal view of what you like, but whatever...I get you are shoppin'.
I guess the only part that sounds a bit dooshy is simply when you are trying to say that the mac air is the best laptop at the best price, period. In reality you have an extremely specific set of wants, from exact screen size to exact weight and keyboard style and focus on battery life, but are willing to overlook things like lack of touchscreen, or smaller HD capacity and slower HD speed (for being a SSD). It makes no sense how you push the exact laptop you want as a universal truth of what is best.
I know at the same time I come off as a sarcastic ass about everything apple. The truth is that I have fallen for the promises of apple one too many times and I am jaded over the way they operate. It gets annoying the way they dictate and tell me what I want and don't want. I mean, just look how apple still today wants to tell me there is no need for a right mouse button. After years of ass-backwardsry, they finally caved a few years ago, but only will have it as an optional side feature that has to be specially configured.
As far as the touchscreen bit on the Asus goes. I must have links the regular model instead of the touch model. My bad. They were both on sale on Newegg yesterday, but now I see that sale is over. I wish I knew what the touch model was going for. You point about touchsceen being important for a window machine but not a mac kinda makes sense, but if I had a windows 8 with no touchscreen, I would just get the classic shell start button added and call it a day. Meaning, I think it can be equally as unimportant on a windows 8 machine.
As far as processor goes, no there really is no significant processing difference between the 3rd and 4th gen. Really. The only notable upgrade the haswell introduces is less power consumption. I think there is some caching improvements, but not really impressive enough to worry about. So it helps the battery, but that is viewed as a different spec anyway.
And you can argue that the thunderbolt is an improvement over HDMI, but there are are a number major flaws with that logic. First, you say the reason you would want it is to hook up dual monitors for a home station. Lets forget completely that the zenbook I linked has both an HDMI and Mini-dvi port for such a purpose. Even if this wasn't the case, a standard laptop docking station generally offers dual monitor support. And you are still gonna need a docking port for your thunderbolt. There is only one port for many functions, why plug it up with your monitors?
The other flaw is that you are praising the mac for money savings, but if you really want to use the thunderbolt dual monitor feature, then you are gonna need to get thunderbolt monitors. Those are far more expensive than regular monitors. Like $1000 for a 27 inch as compared to $300 for non thunderbolt. Buying two would leave you spending $2000 on top of your $1000 laptop. Are you really gonna tell me it is an improvement to have a thunderbolt for dual monitors, and tell me how you would be saving money with the mac at the same time?
I think it is also worth saying that there is simply not as much support all around for thunderbolt. Having anything thunderbolt right now is gonna add a hefty premium. Also, who knows if it will really take off at this point. Firewire was a huge pain for me with my past macs. Just simply finding and buying a firewire devices sucked, and to top it off, I couldn't use them on my PCs. For what its worth though, I really do think thunderbolt is a step in the right direction, I am just not super optimistic about its future and won't early adopt on anything that will cause me to spend more on its peripherals.
