Honestly I'd take that over the hostile vomit that is the google playstore. That thing is an offence to my senses...so many colors and animations trying to grab my attention.
It'll show you updates you haven't done since whatever time period I haven't figured out, but to actually check, from there you have to click 'Manage', then 'Updates available', then 'Check for updates.'
Typically, I have nothing waiting for me in updates, and have to do the above to expose 8 or so apps with updates available.
Absolutely. I'll search for a GOOGLE app to install on a new phone, and it's 3rd on the list, with two completely unrelated apps showing up at the top, waiting to be accidentally clicked and installed, and probably then start popping up ads and other malware.
