That's true. OF is the king of all GTD task management systems and have been since always. It's the only thing I miss after abandoning Apple ecosystem years ago. People who don't do GTD religiously (and believe me - for them the GTD management system IS far more important than anything else in their toolbox) and other similar methodologies tend to have no idea what kind of difference a good system like OF makes. The guys behind the product nailed it and even now, as far as I know, no one was able to replicate their success.<p>I'd be in heaven if the company behind it - the OmniGroup - would be willing to: 1) Develop native or semi-native apps for multiple OSes + a web app; 2) Cut down their pricing a little bit. A similar strategy got Evernote a lot of users (although they still don't have a native Linux app) - I mean cross-platform and the fact that they offer reasonable discounts to their loyal customers.<p>It's also a fact that there's a lot people grounded in Apple's ecosystem purely because their dependence on OF (some even write about that here in this thread). I'm sorry for you guys. Really. Leaving OF was probably the hardest technological decision I've ever made, and even now - years later - I feel a thrilling fear remembering how I was struggling with myself about that, but I really can't afford being into a vendor lock-in with Apple or anyone else for that matter, whether it's in enterprise or my private life. That's dangerous and must have consequences in the future regardless of your current views regarding what Apple does (take a look on how many Fortune 500 companies went off that index during a typical lifespan - Apple isn't eternal too).<p>But somehow MacOS is a very important thing in OmniGroup. Their choice... But I miss you guys and I hope you'll mature to a similar decision I made - that Apple isn't "the one" and life has a lot more to offer ;) We could be friends again. I'm sure there are many others like me...<p>PS: People recommending some simple task management systems they use have no idea what they are talking about trying to compare it with something like OF... It's like comparing Windows' Notepad to Vim. Yes, they both are text editors, but the latter one is kind of "on-steroids" to the point where it makes no sense to even compare them.
