I like it when Apple people post how windows gets virus but have no idea except to repeat this over and over again.
I have had 4 updates on my Ipad and 2 of them are security issues. That is since what? October? Plus you should see the number of problems users are having with the update not working at all.
I use the Ipad a lot, but you have to do everything Apple's way.
That is why the Android is much better for users to like to do things their way.
As far as the Surface goes, it is catching fast and is less expensive for what you get.
All will do the job depending on what you your job is.
