I've had an Apple laptop since the days of the DUO 230, and found 'true love' with the 17" over the past few versions.
The 17" screen just 'fits' my work style and eyes right. All of you folks that tell me to "move on" or something like that are just not getting that - yes we hear we're only 1% - for me and many others, its the computer that does it best for us. Why should I NOT be UNHAPPY if Apple has truly discontinued the 17? If Apple discontinued the 15" I wouldn't be telling you," you could do the same with a 13", so why is it there is a 'tough' attitude about a model that some of us want and need?
And no, a 15" retina is not the same, and the size of a 17" is not a problem for me, its my desktop that moves around the house and in the car to another desktop.
