Even if you did have four usb devices, there was a wonderful technological advance a few years ago when USB became standard- and it is called hot swapable devices. I see it like this- if you have so many devices you most likely are using the laptop at your desk at work or at home so you would be better off using a plug in USB hub where you have all your devices plugged in directly, then you just have to plug in your one usb cord for you hub. Then if you are on the "road" you plug devices in directly. With wireless access to printing, etc. there is less of a need for ports. The only argument I could see for another usb would be if you use a wireless mouse (like I do) and then you have a iPod shuffle, and want one more port. But since I only charge the shuffle every once and a while it is often not necessary for another port. Just my opinion. I like having a smaller laptop personally and will just hot swap when necessary.
