Ever since having bought a MacBook Air back in 2011 which had a SSD I just never looked back. A spinning hard disk drive is the obvious bottleneck in today's computers. Currently I'm using a 13" (Retina) MacBook Pro with 512 GB and this is the first laptop I haven't upgraded on an annual basis. Bought it in 2013 and I'm still more than satisfied.
I still use hard drives for mass storage though and have currently five of them crammed into my Drobo.
