Not to shift focus too much, but I'm kinda surprised so many people still don't use internet on their DAW computer these days, I suppose out of fear for viruses and malware? I haven't had a virus on my computer since Windows Milennium, And if you're worried, Microsoft Security Essentials or indeed AVG Free should do you fine. Generally speaking one could do without either of those if you simply don't browse "iffy" sites or open email attachments called "thisisnotavirus.exe".
I couldn't imagine not having mail, wetransfer, updating, dropbox and online authorization on my DAW computer.
