No lag here at work or at home. At work I have a keyboard, optical mouse, iPod and the Pico all plugged in via USB.

My friend recomended me to buy one, and I could really use one. Just wondering that if I use it with a laptop, will there be a significant amount of delay/lag if I plug in other USB jacks like a mouse, etc? I heard the weakness of USB input is that the bus speed is limited and it may slow down if something else is using it as well.

I don't like laptop's staticyness when I plug my headphones directly in =.=

Also, price? I forgot lol

Most computers should have two seperate USB buses, ie two ports will share the same bus and the other two will share another one. I know all my laptops (PC) and computers I've built have.

I think my system has 5 buses (10 total ports possible), but at any rate I've not noticed any decreased performance in my other devices. Considering that a stream of 16/44k audio is only about .17MB/s, there is plenty of bandwidth left, even from a USB1 standpoint.
