I was looking at iCloud, checking out the service, when I found that you have to subscribe to the service. Not much in money atm, but I don't want a subscription service, so I left the page, thinking that since I did not agree to anything, it was just a search, I would be left in peace. It was evening so I closed down for the night. This morning it came back again! Trouble is, I wasn't able to leave the page. I keep getting their ad on my safari. This one: http://www.apple.com/icloud/setup/mac.html. This is very annoying and blocks my ability to use safari to search with. At this rate I am going to switch to another search engine. I have never seen such aggressive and persistent advertising! It also comes up if I open a fresh window. I tried removing the ad, but it now comes up as a page of detailed instructions. I have never seen such aggressive and intrusive advertising!
