Very confused by this. As far as I know it's standard for lenses to be custom made for your frame even when you purchase them at the same time.

I just sent an old pair of glasses to eyeglasses.com for new lenses. I never considered this to be a big deal.

Yea...you can get a nearly identically specced ASUS for $300. This is a compromised low-end laptop at mid-end pricing.

RAM is on the package not inside the CPU. Maybe possibly some performance boost from that but the benefit is mainly improved packaging.

Windows Phone 7 was another OS. Windows Phone 8 was the next totally incompatible OS just couple years later.

Opteron was a much bigger deal than you're making it sound. Market share was up to 25%.
