I agree, and I am, and I do.

I held out on laptop from 2009 until recently, it had a core 2 duo, It was (and is) a really good machine for showing up sloppy performance hungry websites, and has been the source of a few of my rants here on HN when discovering some stupid side JS animation saturating one of it's cores unnecessarily.

I agree there's a lot of shitty JS code out there. But there are a few of us web devs that care, and will do anything we can to prevent the crap we see around us.
