If "cost" is quantified as hardware cost, I wholly agree. But "cost" can also be quantified as the real estate on the side/back of a laptop. AFAIK, I believe the PS/2 connectors have virtually disappeared from laptops.
Interesting point! I still see them on some laptops, but mostly the sort that also have docking stations -- docking stations pretty much always seem to have PS/2 ports.
"Cost" can also be measured a third way: the degree of simplicity of the device for naive users to correctly use. I think it's safe to say that Apple pays far more attention to that "cost" than any of the PC manufacturers.
Yes. Although...
Long-term historically, Apple had a history of making things easier for naive users at the expense of extreme hostility to the needs or desires of non-naive users. OS X has mostly been a move away from that, but their new MBPs strike me as a bit of a step back towards that. Offering a militantly-simple experience is great if, and only if, all the things you want to do were represented in their focus groups.
I was totally looking forward to the new MBP, but it seems to me that until something like this docking station exists, I can't actually USE the new MBP. (And since I hate Belkin, but use Firewire, I may be screwed anyway.)
I am in the unfortunate position of liking OS X but being outside Apple's main demographic these days.

That's why I'm saying that 97% of usb ports were shipped in "windows pc world".
Not early on -- early on, many PCs didn't have USB.
But frankly iMacs didn't change anything in kb/mouse market in whole.
AFAIK at least for the next 5 years (1998-2002), most pc's still shipped with keyboards with ps/2. And many still uses them. Mouses began to change to usb when laptops took the lead in market and again I don't understand how macs could have affected to this in any way.
I can tell that you don't understand. Let me try to explain it.
In the absence of the Mac, it doesn't matter how many PCs ship with USB ports, because every PC ships with PS/2 ports. While the PC users could in theory buy a USB device:
1. Every PC user can also buy non-USB devices.
2. Most PC users already have devices that work.
3. The non-USB device will work with other PCs they may also have or still use sometimes.
So for the PC market, even if 90% of machines ship with a USB port, you're still better off selling PS/2 keyboards.
Enter the iMac. Suddenly, there is a new market. It's a small market, but in this market, ABSOLUTELY NOTHING can sell unless it is USB. Period. Every user in this market is in the market for USB devices. They cannot use non-USB devices. They will not prefer non-USB devices for compatibility, because a non-USB device won't work for their primary machine. They cannot continue using their old keyboards and mice.
Now, that can be a small market, but it's a market that is easily targeted and has the key trait that
none of the devices currently on the broader market can compete in it. If you make a USB keyboard for the iMac, the hundreds of PS/2 keyboards out there
are not competing with you.
Niche markets can support products, especially niche markets that have the key trait that their members
cannot buy something else. This is why that godawful memory stick format exists -- because Sony makes things which use that format, so people who buy those things
must buy memory stick media to go with those things.
The difference is that, as you note, the PC market has lots of people with USB ports. And now, watch the magic:
When it was PS/2 vs. ADB, it was basically impossible to make a single device work with both, although you could sort of fake it up with a special switch and cabling (I had a keyboard which could do that).
When it was PS/2 vs. USB, suddenly you could get a keyboard that worked on your Mac and on your PC, because the PC had USB support too.
In the absence of the Mac, there was no advantage to USB really, and most people just kept getting PS/2 keyboards that worked with their old stuff.
But once the Mini showed up and created a market of people who would only buy USB, no matter what, there was a reason to make a bunch of USB stuff. And once you were making USB stuff, you could sell it to PC users too, because hey, they have USB ports. And the compatibility with the Mac became a selling point, and a reason for people to buy USB instead of PS/2 keyboards.
So, yes, it was a really tiny market, but because it was
monolithic -- absolutely everyone in it would buy USB, none of them could buy anything but USB -- it was influential.
