I am a carer for my wife. Both of us use an iPad (first edition). I run os x Lion on my iMac. I also have Vista via bootcamp. My wife has a Windows computer running Win 7. There 's also a spare windows computer with Vista installed. Two computers are connected via Ethernet to a D-Link Wireless N150 ADSL2+ 4- port Ethernet Router. The Model is DSL-2730B. The iMac is connected via WiFi as are the two iPads. Regards to everyone.
