If it was my only alternative to baidu, maybe.
You type some phrases into an app, the app displays results in a webview, you click the SERP, then what? a browser opens?
Why don't you use the browser on your phone directly for searching?
That's why I think Google is working on some ROM feature, not an app. Or maybe there are some misudnerstanding from the "source"
If it's an app it's doomed to fail.
These are not exactly web page search. It need deep integration with account(gmail), maps (with up-to-dateupdated POI), schedules, music, movie reviews, news.
It covered much more than just search. I am not sure google can pull that off the same app in China. It will be very unlikely.
