The clue is in this part:
>That makes them an interruption, not a notification.
>And interruptions are a bag of hurt when you have things to do. I for one turn off as many notifications as possible.
If i get a new email i dont mind a tray icon appearing that looks like an envelope but i DO NOT want a notification, or the taskbar button to flash, and i certainly do not want it to leap to the front of the screen. I would like to get on with doing whatever it was i was doing and check that tray icon once every hour or three to see if any emails have arrived.
On a slightly side rant this is somewhat related to the way my mobile phone OS (Sony Erricson) annoys me. I leave my phone on silent 98% of the time - unless i'm expecting a call basically, and if i get a missed call i'll phone that person back, or sms them or email them at MY convenience. But my mobile shows a red icon and a splash screen saying basically "OMG YOU MISSED A CALL!!" and i have to open an option menu, scroll down three items and select "Dismiss" to make the splash and icon go away, it then says "ARE YOU INSANE!? IF YOU DON'T RING THEM BACK RIGHT NOW CIVILISATION MIGHT END!!?!?".
And I click "Yes, Fuck Off"
There's a Ray Bradbury short story about this, it's a good few decades old so muses about intercoms, fax machines and telephones but it ends with a guy sitting at his desk not getting any actual work done because he's constantly switching between them, all to the background of muzak. Sound familiar?
