Broadening Aquaria to other platforms may be profitable and worthwhile. How about the Wii for example? It would be great, and with a little work, Aquaria could take advantage of its Wiimote.
I don't know about other consoles. To be honest, I don't play them.
Would Aquaria work on the Nintendo DS?
As for Mac vs Wnidows, I have a better comic:

Seriously, its rather futile in the end. Preference and taste. Some people prefer Windows while others prefer macs.
To the original point of that, I think that porting Aquaria to macs can work if they allow it.
As for Linux, then it really comes to apples and oranges. Linux has many versions ("distros", I think) and are really more for people who are computing experts and prefer to work in a more controlled environment.
Just because one laptop generated extra heat is no reason to change the well-known term.
I agree.
Furthermore, when you put a block of complex electronics that conducts heavy traffic, heat is expected. Because, ya'know, its kinda how electricity works. Conductivity, the principle behind transistors and that lot.
