I'm the OP
As others have commented... "launch the program once and then it's faster to launch"... that's true... but I can't launch everything I might need before I need it... then my boot times would be unbearable.
I use the computer for a variety of tasks throughout the day, for programming in Java/Eclipse, web browsing (news, macrumors, slashdot, etc.). I also talk on the phone with customers about prices and discounts. That's where the calculator comes in... I might be on the phone with a half dozen programs running and tell the customer "we can give you 15% off the price..." previously, on Windows I'd just hit the Calculator in the task bar (no matter how many programs are running) and it's on the screen before you can even start typing... NOW, I have to tell the customer "hold on... just a sec... I'll have those numbers for you... my computer's acting up..." blah blah blah... while the thing starts...
Basically it's just really annoying... I can tell nothing is "wrong" with my system as the issue is consistent across all applications ("slow" initial launch time).
The GUI for the Macintosh is already 'loaded'... I can't imagine anything the calculator uses that isn't already 'in memory', it doesn't use any tricky GUI or graphing functionality... it *should* literally popup instantly... not even a half-second... and you can't honestly tell me the calculator for the Mac is 'prettier' than Windows... it's a calculator...
(you know, I've got an idea... let's see if starting the Windows calculator from VMWare unity is faster!)
