Just made the switch on my wireless laptop. So far I like it. On restart or coming out of standby XP was having trouble re-establishihg my connection. No problems with Comodo. Over all PC start up and response seems a bit snappier too. Browseing seems snappier with Opera. Time will tell if the trend remains. Not sure I will make the switch on my 2 desktops.......but all is good in the land of laptops.
