same goes for another major Chinese phone producer, their virtual phones in browser are just horrible, something I would check even with screenshots and Excel in 30mins take with virtual phone 1.5hour, complete waste of time
I am yet, to experience any web based tool which would be superior for my work compared to offline apps
oh, now that I mentioned it, certain big Japanese phone brand have really nice web tool where you can work superfast no problem 150-200 screenshots per hour including editing and highlighting bugs, but that was only exception to my experience with all other companies
However, I did use the Studio few times and I didn't like it for the same reason you don't like web apps - it was big and slow like molasses. I did most of my work with (Trados) Workbench and TagEditor - these were lightning fast compared to Studio.
So I guess, that it comes in cycles: fast forward few years and people will be complaining about the latest tools and how the previous web apps were quick and easy :).
Most people I know seem to prefer the old Workbench. Big customers are also switching to web-based tools, where they can, among other thing, track the progress status easily.
