Why would Linux (or Mac etc.) users be immune to Phishing emails asking for bank details or account passwords? It just doesn't make sense.
Linux users also get bombarded with virus emails and have their email addresses stolen from other peoples outlook address books and faked so we get bounces telling us we have a virus. We don't actually get viruses but still, when your network is clogged with thousands of such virus emails you still can't work on the internet in peace.
Not to mention the time spent cleaning up family members' machines.
Don't think that just by moving to a sane platform you can totally escape having your day ruined by Microsoft's mistakes every once in a while.
