The SSD was / is fast ... the extra RAM now means that his multitasking applications are just much more responsive... no lagging or hourglass catch-up.
Back to his SSD...
The Windows Experience Index is not really anything to go by, but it jumped from around 5 with the stock Apple 5400rpm HDD to 7.8 with the Corsair SSD. His MacBook gets to Windows desktop from power on in 11 seconds... Outlook, instantly open, Word, Photoshop etc... all instant... no longer than 3 seconds splash screen delay. Indesign CS6 is the most impressive... with all the plugins and such it used to take a good minute to settle down and become usable... now it is around the 15 seconds mark. In everything he uses daily, there is almost no waiting. Resume from hibernation in around 5 seconds... sleep instantaneous.
Jaw dropping.
EDIT: When he 1st got the SSD, he would just boot the MacBook, open Outlook and perform a couple of search queries, do a few SQL database queries, launch Indesign and edit a huge file, and then reboot... for around 20 minutes... repeating the sequence.
Each time he would just look around with a glazed look of bewilderment on his face... and repeat to me "OMG... do you know what this means... do you really understand the implication of this... this is a dream... this cannot be real... OMG".
