Google always strives to make things Simpler to develop and Easier to use !
GWT benefited tremendously from the advancement of App Engine !
Its also blessed by SpringSource which directly integrates into APP Engine through the ground-breaking Spring ROO. So this means less steps to follow and less boiler-plate code to write! save time by avoiding infrastructure-setup
Actually it saved months of work in couple of projects !
How about scalability and performance ? Its a good time to adopt Ext GWT !

Well ! GWT is for Java Geeks ! How’bout common masses who just owns diverse set of data – ranging from – geographical info, traffic data, weather info, chemical properties, physics measurement data, population info – Hey we just want to visualize our data – we hardly care about building an App !!
Here comes Google Fusion Table – it will load your data into Cloud (read Fusion Tables) and display/ report in Visualizer UI.
