PC Viruses are a remarkable non issue on iPad
It just occurred to me today that using the iPad to view my email reduces the exposure of my PC to viruses.
I don't know whether there are any viruses that are targeted at iThings yet.
I definitely use the iPad to view questionable messages as I know they can not affect the iPad like it can a desktop.
I also use eleven Gmail accounts with a rule to flag messages with an attachment to be labled with a big red DANGEROUS so my wife an others will be cautioned not to blindly open them. My wife sees that on her incoming mail on the desktop and she immediately deletes it without opening it which I approve of.
Dangerous virus issues in Windows 7 is such a pain in the donkey to deal with, much less so on Mac Snow Leopard.
The iPad also does a fairly good job of protecting you from bogus web sites that use FLASH to compromise you desktop as we know FLASH simply does not work on the iPad.
Phishing is still an issue if you are dumb and do not recognize it. We got one a couple of days ago that looked like it came from Wachovia Bank but without using any information in the email or the web site it directed us to we immediately contacted Wachovia [Wells Fargo] account security by phone using a number from our own records not the email's and determined it to be false. Probably thousands subcummed to that one but we spotted the differences and danger by looking at it with the iPad after seeing its message header on the PC. This was a well done attack IMHO and I feel sorry for those it nailed. They may not even realize it yet.
