    I mean, is it any less difficult to plug in a USB mouse than a PS2? I don't understand the advantage of one over the other? Can someone explain this?

    Convenience. USB is a hot swappable device so you can plug it in after the system is on and it will work fine. Makes a huge difference for a lot of laptop users. Other then that there really isnt any "Advantage" to speak of.

    Consolidation. Makes sense to have a 'universal' bus, instead of Keyboard, Serial, PS/2, ADB, whatever Sun called it's old keyboard/mouse bus, and so on.

    Makes it much more likely you can buy a piece of hardware, plug it in, and go.

    The USB bus is also faster than the PS2 bus, so you get a higher sampling rate on USB mice. Some 3d Gamers say this makes a difference in the responsiveness of the mouse.

    What Don said. I remember there was a big hoopla over this when USB mice were first being released.

    I haven't noticed any different.

    I use a USB mouse cause I have two mice plugged into my system.

    You can also buy an USB hub and plug everything to for convience and relocate the computer elsewhere instead of having to use extension cords for each device. There are also people who use the serial bus to connect to other devices (routers, other computers, joysticks, etc) and end up using the USB port for the mouse. Personally I think the convience of it being on the front of some computers allow people to also get varied type of furniture instead of being based on the cord length of the mouse.

    Noticing the mouse speed depends on your frame rate. If your frame rate is significantly higher than your mouse sample rate you'll notice when the mouse sample rate is increased. Although with the PS2 rate programs out there this is really a moot point.

    The bigger one with keyboards would be how many keys can be pressed at the same time. I hated the old 5pin keyboards. Playing games I'd always be pressing more than 3 keys at the same time. With the 5 pin if you are holding 3 keys, the 4th key you press does nothing.

    With PS2 this goes up to 5 (I've never managed to hang up a PS2 keyboard pressing too many keys, but my roommate complains about it). And I don't know if there even is a limit with the USB keyboards.

    But I do think the biggest reason is what Shayne and Robert said.

    I have two mice as well. One is a trackball and one is a mouse.

    A USB mouse vs a PS2 mouse in a first person shooter game is night and day.

    I could never go back to the jerkyness of a PS2 mouse.

    The other reason is that PS2 connections and all legacy devices are going out the door, at least they have been trying. There are no needs for such old architecture now.

    Mainly to get it down to one interface. It eliminates the need for seperate serial/keyb/mouse ports.

    I believe the default (in windows) sampling for PS/2 mouse is 40hz vs 125hz for USB. You can change the sampling rate to higher, however. I find a higher sampling rate very noticable.

    Having a hot-swappable mouse is much nicer.

    Mac users wonder what the purpose of a parallel port, a serial port, a game port, and a PS2 port is. [​IMG]
    USB is the only option we've had for keyboards and mice for a few years now.

    My new motherboard, the Abit IT7 no longer has "legacy" ports like the keyboard/mouse PS/2 ports, serial ports, or parallel port. It has a shitload of USB ports (10?) and 4 firewire ports.

    I'll have to agree with Jason as when I took an A+ course one of the things we were specifically not taught were Apples since we were pretty much told they were such inferior business machines that it wasn't worth the time to learn them for the test (consider we were tested both for Dos and Unix this told me that apple doesn't have much of a market representation).

    For the record, OS X is not based on Unix. At least, not directly. It's more accurate to say it's based on BSD...specifically, FreeBSD...which is a variant of Unix, similar to the way Linux is a variant of Unix. Another version of BSD, I believe OpenBSD or NetBSD, is probably the most stable modern OS available. Nobody has found any remote vulnerabilities in it in over four years. For the record, Windows is my favorite OS, but we all know Microsoft can't say that, and neither can Linux.
    Oh, and about Mac users wondering what all those other ports are for? Hey, when you figure out that mice should have more than one button, let me know and we'll talk then. [​IMG]
