Email... loads of choices, google mail for one, dead easy to set up,
there's Yahoo etc as well.
Virus protection and Vista. For me now, having used this for a month or so there would never be any going back.
I have nothing against others but having seen how little impact this has on performance, and the fact that it's 100% compatable with Vista means I wouldn't use anything else now.
Be aware that this IS a beta program due to be released within the next few weeks, but I would seriously consider this.
Also use only one AV product that operate in real time.
