narrow minded folks who probably never use their Mac laptops in mobile environments where you can not avoid making contact between your wrist and the body of the MBP.
Try riding a train, plane or subway and keeping your wrist elevated like Mavis Beacon taught you.
Or even when you just sit on a couch with the laptop on yout knees. Some people will tend to rest their hands on the computer to prevent it from sliding back.
But I guess you guys think the power button on the back of the Mac Pro/iMac/Mini is brilliant, and the SD card slot hidden on the back is no big deal.
