I used to use outlook but it only took paid for accounts (i have bt and other accounts that i don't use).There are/were benefits with premium such as unlimited memory, massive in box, sending pics inside mail etc.
I have five computers the huge imac, and a work book pro- these catch all the emails paid or not without me having to do anything.
I use a little acer for wcp, work and printing (it won't run on apple) and bank reconcilliation.
The other thing about the apples is that you don't need disc drivers, you plug them into a printer and the work.
But still got the email problem.May have to do with windows live.
