i know an engineer in a fortune 500 company up until last year they still used lotus, just switched to the microsoft suite, the reason, there were too many complaints from the contrators (of 10 years) that they have to deal with lotus files and conversions.
oh, but they are still fighting to use xp, new dell laptops get downgraded from windows 8 to win xp, i laugh and say, then what is the point of these laptops having 6gb of ram lol.
