The cost of having 1 Mac was much less than having the hardware to test everything, plus at the time I was financially able. Qt4 expands on this reasoning and lets me develop one codebase for all platforms, leaving me open to focus on more on the product and worry less about where and how.

PHP5 string concat performance debate
Just did some unscientific but interesting tests between php’s concat and php’s double quotes. I heard once that doing single quote concat with . was faster than double quotes. So now we will see.
