I get the idea, but I don't see the point. I'm all for the iPad, but I don't get the keyboard accessory. That's merely marketing it for people that want a physical keyboard to type on - and that market segment is already held by every laptop and netbook with a physical keyboard. While it's an interesting accessory and will probably be useful for some people, it's purpose has been filled years ago.
The people that want a physical keyboard will turn to the laptop, with the computing power
Clearly you DON'T get it.
I want a mid-size tablet (9" or 10" specifically). I want it to do common tasks and light weight tasks (web surfing, media playing, rss reading, document viewing and maybe light editing, note taking and review, and then for my quirky needs, ssh and vnc/remote-desktop). I only SOMETIMES need a keyboard, not all the time. MOST of the time, a keyboard is wasted weight that just gets in the way. I only need a keyboard in a few situations (taking notes, for example).
My experience with netbooks is: the keyboard is always wasted space. It's too big to thumb type, and it's too small to touch type. It's ALWAYS better to use an external keyboard when you want to really type on a netbook. And when you don't need to really type heavily, the included keyboard is just awkward.
But to say that I would, instead, get a laptop? You're on drugs. Heavy, debilitating, drugs. A laptop is WAY TOO BIG, too expensive, and a complete waste of CPU power (like I said, I only need to do common and light weight tasks; why pay for a heavier class of CPU, Disk, and RAM than what I actually need?).
No, the correct answer is: a mid-size tablet, that has built-in USB and video-out. When I don't need to type (just reading), then there's no useless (netbook sized) keyboard in the way. When I need to do just the most basic of typing (navigating menus with single character strokes, short phrase entry, short message entry, etc.), then an on-screen virtual keyboard is good enough. When I need to do REAL typing, I can get a full size folding USB or Bluetooth keyboard to fill that need.
I don't need to waste money, electricity, nor waste space in my gadget bag, on a laptop. I don't want/need a netbook sized keyboard. Nor do I want/need a laptop sized keyboard (when I want a keyboard, I want a REAL keyboard).
The problem with the Keyboard Dock for the iPad is NOT that it exists. It's that it exists as a hard-wired keyboard. It should have a USB port (or two) and a Display Port connector, so that you can use a real keyboard (or an ergonomic keyboard, or whatever keyboard you choose), maybe a real monitor (and maybe via a KVM switch).
But your idea that people who want real keyboards will step up to laptops is completely laughable. And your logic behind it sounds like you've been OD'ing on cough syrup.
