I proposed a revamped home computer network to my home financial controller (Jenny). Yippee! It got approved. Her observation was "looks like a small office". True - laptops, server, DMZ, Internet gateway, WiFi and maybe a domain controller. It'll take sometime to research it and start implementation.
First steps is a new laptop for Jenny based on the Centrino (Pentium M) chipset. Top contenders are Dell Latitude D600, Toshiba Portege R100 and IBM Thinkpad X31. Also looking for a good 17" LCD monitor.
