Lack of support for Linux is a consequence of not being a webapp, and that is what I really don't like (even if this was supported on Linux, OpenBSD and Solaris). Is expecting that Google can deliver cutting edge web-based apps really weird?
The design crowd probably are using a Mac or a Windows..
(it took me a minute to see PC = Windows, and remember this is a "machism" for Windows)
Linux is a thing mostly for coder types, and probably would want the source code attached to it.. and probably since they dont want tho share this code with us.. no Linux version for now
But you'd have to go out of your way to get your hands on it since the Download button is inert unless their javascript can confirm that you are in fact using Windows or so. Doesn't seem to work with wine's built-in browser, and I couldn't get past the clickwrap EULA with an old chrome-based browser running under wine either.
I would also like linux support, but it still looks like an impressive suite regardless.
