Yes the rumor did say a redesign I know. If you read my post, all I did was basically color one black for the people that like the black to see. I had no intent on trying to design Apple's innovative new laptop. I work full time and go to school full time and it's finals right now, I have a life lol. I can't speak for others but I pride myself in thinking out of the box however, I promise you that when the new laptops are announced they will look something similar to the mockups you have seen in here. How much can you change a laptop without implementing future things like the multi-touch surface etc. I know Apple is going to do that in the next couple years, but not right now. It is still going to be a wedge with a screen and a keyboard for now lol. So maybe you should learn photoshop and start some mock-ups of your own or start a company that thinks out of the box which is what I am currently in the process of doing 
I agree, we are all busy, and I am not asking for a sweet new mockup with great curves, just that if you are going to do it don't take the lazy way out (for those that did) and photoshop an iMac onto a MacBook Air.
I would love to make a mockup but Apple doesn't pay me to do so, or think about what their computers look like. I have a job and a family, so I don't waste much of my time on things like that. I know photoshop more than most, trust me, 90% of the shooters in the photography forum are really showing me how users don't utilize photoshop correctly, and a lot of the mockups show me the same thing.
Making a mockup correctly, is probably better done in Maya or a CADD program, otherwise you are doing what is being done, pulling someone else's work and pasting onto something else.
As for designing something different, take a look at every other PC maker. They are wedges with screens and keyboards, but they all look different. The Air looks different, and no matter what people say the MacBook looks nothing like the iBook.
Trust us, every time there is a mockup for a new proposed Apple product it looks nothing like the actual product, not even close. From the G5 iMac to the Al iMac, iPhone, iPod touch, even.... the MacBook Air. But as you say, most mockup artists don't have the time or proper tools to make the mockups, but the Apple engineers and designers do. Since mockups artists don't put as much brain power into it
(I am sure Apple and Ives are discussing design with a bunch of professional designers while the mockup guys are doing on their own accord and what they think is cool, rather than what's really different.) the designs come out looking rather childish at time, and other times they look great, but we know they won't happen at all because it's against Apple's design motif.
p.s. No one is bashing the skills of the artists, just their motivation. So for all the artists out there, good job, don't let laziness stifle your innovation, think outside of the box and stop accepting
mediocrity.
