The Wonder Of Microsoft Paint. - Created with Haiku Deck, presentation software that inspires
Although I consider myself a Mac person, I'm not slavish about it. Microsoft does a few good things. Publisher is good, Excel is good, Word is good (although the latter's gotten bloated lately). I even have a Microsoft webcam (it doesn't require drivers and works with every program you throw at it).
But my favorite Microsoft is free - Paint. It's light and simple and just does what you need it to do, no frills. One of Apple's dumbest decisions was to get rid of MacPaint, although you can download a free app called Paintbrush that is similar. But, at work I can't install anything, so Paint is a real lifesaver when working on flyers or presentations. I even wrote this little ode to Paint in presentation form.
Do you guys have any little programs that don't get a lot of hype, but save your bacon?
