So I got an email and it mentioned the Founder's Edition, and I said to myself 'Hey, look, it's still available! Let's get a copy!'. On the site, I read all the info, thought the Founder Ed sounded good, but the Lifetime Founder sounded better. Then I read the system requirements... Windows only? No Linux client, OK, no Mac client either? Nothing?
Windows is at a real inflection point, and users are pretty fed up, even if they're not sure what they're going to do about it yet, and I'd recommend becoming OS-agnostic sooner than later, so that you can remain flexible.
Just my 99$ worth, I guess, since I no longer have nor want any Windows machines in the house. Please commit to a Linux client, and I can guarantee at least one Lifetime Founder sale.
