I can relate to wanting the latest tech for sure. But saying it's because they have good residuals is kidding yourself. If it's worth £1k in 3 years (it won't be) then that's still £1k it's lost. Which is more than most normal laptops (where you could still sell them, or throw it away and have saved money). MBPs sure are pretty though!
The aesthetics is just part of the package, the overall experience is 10x that of a windows machine.
I'm not biased, I'm 33 and have had windows machines all my life until 6 months ago when I decided to switch.
I won't be going back to windows unless something significant happens.
