Nathan, that old software argument is tired as hell. You can do anything with free or cheap software on a PC that you can do on a Mac with iWishiknewhowtomakeamovie. Just like the Tricycle analogy, it's just a matter of how much self-edification you're willing to put into it. And for what it's worth, a friend of mine who does a lot of video editing tells me that the new Windows Movie Maker is fantastic (from a simplicity standpoint). Anyway, bottom line is, PCs are cheaper. You Mac guys need to just accept that. You can make "get what you pay for" jokes if you like, but to make flimsy comparisons based off of arbitrary software pricing values is just silly.
Also, superior battery life has nothing to do with the Mac OS, so please don't imply otherwise. The underlying hardware, as has been noted before, is more or less identical from an architectural standpoint. PC notebook makers mostly cater to a different market than Apple, and battery life has always been the red-headed stepchild of when it comes to flashy selling points. It's only in the last year or two that it has become a much bigger selling point because let's face it, pretty much any $500 notebook is going to be touting more CPU and RAM than the average user needs, so OEMs have to find another way to spruce up their offerings.
PC, I wasn't taking a shot at you, just at the guy who wrote the article.
