Add to all this a significant intangible. Underneath all of the gloss and bazillion options for each components there is an undercurrent that is noticeable. Jack and the EXT team are having fun. These components are more than just usable. They are fun to use. I keep noticing these little touches that have nothing to do with usability. They are just flair. And they make it fun to use and fun to build.
I think EXT is a significant competitor for Flex in the application space. I can easily see a company scooping EXT up for millions. Adobe makes sense, but so does Microsoft or Apple. It could be anyone.
I hate to give such a “sweetheart” review. Isn’t there SOMETHING that I would change? Well, for starters, I appreciate it as a toolkit for me as a UX Designer, but in reality, I can’t program a single line in it. Not one. In terms of actually using it, it’s for application developers. Not for the feint of heart. I imagine there will be IDEs and programs built to generate EXT applications. This may help. I’ll have to noodle on other stuff I would change.
I strongly suggest any application developer to check it out.
