Just bought an AAO, with Windows XP Home (licensed), 160 Gb HD and 1Gb RAM while I was on holiday in Penang. From a software angle, I'm keeping it minimalist, to get the best speed. When I took it to my office in Bangkok the technician said I need to upgrade to XP Pro (we have a site licence) to connect to the office LAN/WiFi, because of the way the security is set up. Can anyone see any problems in upgrading? Thanks :)
