Here's the situation. My wife has a PC laptop. I currently have a PC desktop, however I am considering my first mac in the form of a base MBP. Peripherals: 22" Samsung monitor - to be attached to the MBP when not mobie HP LJ2110 AIO printer - for scanning, copying, etc. Samsung CLP 315 colour laser - for printing my business items Seagate 250GB external hdd - For backups Is it possible to use a USB hub or some form of print sharing to allow the hard drive and BOTH printers to be shared wirelessly for both the PC laptop and MBP? Can I use the Airport Extreme? Do I *have* to use the Airport Extreme? Is there maybe a more cost effective solution. Further to that, if I use Time Machine to backup the MBP onto the external, can I use something like vice versa to backup the PC to the same drive? Can they both access files, or do I require some kind of file server for sharing music, etc? Thanks for all your help Mac Forum!!
