And no users of old PCs who face similar problems? No? Well, probably not - if you haven't updated your computer since 1995, you probably don't spend much time sharing files with other people. But this applies to Macs too, y'know...
Naturally.
None, then?
I don't see the importance.
Then answer the question. Do you have any firsthand experience for the strawman argument you are tossing about?
I don't understand why this is important. Please explain.
Thing is, there are absolutely NO software suites in any function for either PC or MAC that do not allow you to save in a format openable by the other.
Did I say otherwise?
