I haven’t really ever bothered using calendar programs as i don’t really need them but when i got leopard i really wanted to see what everything was like so i opened up ical too see how it worked, first impression was that it was an easy to read simple layout and then when i went to add an event it was so easy, just a simple click and drag the time that the event will be and then simple give it a name and that’s it. Even though i don’t use calendars much (software ones) i really liked ical and now i am using it quite a lot, after i used ical i thought i would give the windows calendar a try for the first time as well, the first time i looked at it well right away i knew that ical was better as the layout in the windows calendar was a bit bad and i thought that it could’ve been improved and since the layout was something i didn’t like then i didn’t want to carry on using it so once again for me apple wins another battle.
