Un-bloody-believable. I have been a Mac user since 1982, well Mac since 1984 and even THEN they included the super-useful Calculator as a 'desktop accessory", and migrated to all Macs since then.
Instead when do they offer us??? THREE apps to check stock prices (all the incompetent Apple devs who live in a land far-far away are far too focussed on their stock portfolios rather than useful productivity tools)
I can also get NEWS (2 widgets), VIDEO, PODCASTS and several other useless "tools" which do not improve my productivity one jot, indeed are anti-productive. But unit and currency conversion? Sticky notes for frequently referenced information? (Yes, there are alternatives, but not as handy)
You really missed the boat here Apple, as you have been consistently doing for the past decade or more. When I used to be a researched and lecturer in Human Computer Interaction (HCI) you were help u as the model. Now I look to you for examples of how to consistently fail to understand user task management and instead serve up the fleet crap du jour. Get real.
