Grats to Jeff and Nolan. Appcelerator was once an Atlanta based company and they invited me over to hangout in their office a few times. Very nice guys and a great product; always open to chat startups.

Anyone with experience with this? Does it work well?

I just spent about five hours this weekend experimenting with Titanium Mobile and for someone like me knows Javascript, but not Objective-C or Cocoa, it looks awesome. After spending some time trying to get kick started using Objective-C, Cocoa, Interface Builder and XCode, I would guess that Titanium might reduce the time it would take me to build a substantial iPhone app by maybe 5-10X.

pekpongpaet and chadpaulson used it to win the iPhone hackathon competition at this past weekend's Day of Mobile. Chad claims he'll write a post about it, but if he doesn't, the tl;dr is that it made him a believer.

...but RWW get's the pricing/packages wrong, Jeff explains here: http://support.appcelerator.net/discussions/announcements/28...

They have a ton of videos on their site but not enough info that builds credibility... how effective is their platform? how long will they be around? should I trust them to build my apps on their framework -- what if they disappear?

The platform is open source, so there's no reason it can't survive the demise of the company.

but why is their 'about us' video such marketing cheese? http://www.appcelerator.com/showcase/

i will try their stuff though...
