to save money if you don't want to pay for XP Larry, and never intend to upgrade your other programs, and are content with what you have now, considering that upgrading often entails hardware costs too.

XP is ok since SP1, well supportive of hardware now and superior in its memory allocation and multitasking. My laptop has no floppy built in (SD slot built in instead) no serial and no parallel connectors - it's the similar story in hardware terms; had to buy a usb to serial cable to be able to do unlimited programmable time lapse photography with the digicam and user program the non-wireless mobile phone easily.

But you have no choice when buying a new computer anyway
