I couldn't image carrying around a $4500 laptop
If you're going to spend that much money, and not carry it around, why not just buy a power house work station?
If you are going to carry it around, that takes a lot of guts.
I don't tell rich people how to spened there mony, but for me to pay over $1000 for an SSD drive that will cost less than 1/2 in less than a year.
and with it the value of the laptop don't make sence.
