The full size keyboard with numeric keypad looks and works great. It's a pity it's wired.
I feel that people with MBP would love a full size keyboard for these reasons:
1. Developers like me use the num keypad a heck of a lot. (The ability to do /* and */ quickly is more than worth it, but the number keys, oh, no doubt).
2. Accountants and anyone who use numbers would love a num pad. The ability to pull out the MBP and keyboard out of the bag and have a functional keypad without plugging it in is great.
3. The cursor keys are much bigger and easier to use.
4. A different delete key, page up, page down AND more function keys for shortcuts. Great stuff.
5. Musicians use the num keypads a lot too. Software like Cubase for example has a lot of shortcuts utilising the num pad. Now, here's an important point. With a bluetooth keyboard, the full apple keyboard can be placed on top of the music keyboard. What a convenience, but with wired, yeah, you kinda can, but... it's a real drag.
My point is, a lot of people would buy a bluetooth full sized keyboard.
But there's more reason: Those with macbook only has two USB ports. Most of them are probably already using a bluetooth mouse. So, where's the fullsize keyboard? Also, I love the fact that the power connector of the MBP is magnetic because it doesn't cause much wear and tear over the years. But with a USB keyboard, the USB port is not only used up, but it also would wear out the socket sooner with all the plugging and unplugging. It kinda works against the design philosophy.
So, Apple, what's the delay? besides there's "money" to be made here.... We need it, you can do it.... chop chop...
