This is the saddest thing I've read all day
Must be very early in your part of the world eh?
The Arduino IDE is but one example.
Maybe but not a good one, it's pretty ordinary and I never use it unless it's to see if a code example compiles before I post it here.
Probably not much of the stuff I use (Altium, CorelDRAW, PTgui, Photoshop, AVR Studio being the major ones) is available on Unix. I know there are often equivalents (eg Photoshop => Gimp) but I don't want to relearn all that crap. And there's still the new license issue. And then I have my own VB apps I've written over the years.
I looked at Open Office a while back but I don't think it had an email client.
I'll look back into it, it's been a couple of years and these things change a lot.
