Hmmm... Well I know that I still love my pixlr (the advanced editor).
Pixlr is actually available as an Android and iOS app as well, so you don't have to actually be connected to the internet or upload anything to use it.
And the thing is the on-line version Pixlr, like Google Docs, is blocked and censored here in China, and is inaccessible unless one is using a VPN. Which means if anyone comes to the "People's Republic"

, they're not going to be able to edit their photos with the Pixlr web app, unless they've paid for a VPN.
BTW I've seen a lot of frustrated tourists going up the wall, just because they couldn't access Facebook.
Aviary pulled the plug on their web apps, they now do a photo editing app that can be used off-line.
I feel like web apps gained steam for a while. Right around the time everyone was trying to sell cloud space. The other thing is that you must understand what a web app is, technically when you go to phandroid in the browser, or any forum for that matter in the browser, you are technically accessing a web app.
I can understand having to be connected to the internet to read and post on Phandroid or any other forum. But years ago when I was active on usenet(newsgroups),
I was using an off-line newsreader, that would download all the posts, I could read and reply to them and then upload my posts in one session when I was next on-line. I used to have a driving job, when there was no mobile data, but I still liked to read and post on newsgroups during the day, when I wasn't on-line. I would upload my posts when I got home.
Sure html5 apps aren't quite what they were expected to be, but that's not the only kind of web app.
Thing is, I don't really want to have to be on-line to do some word processing or make a presentation and store them all with a
third party in the cloud. And would be inaccessible if I was on a plane or something. I also don't want whatever third parties and governments having access to all my stuff as well, some of which might be confidential to me.
Baidu offer some on-line web apps, along the similar lines as what Google does, but if you do something that's politically sensitive or undesirable, you might find it will mysteriously disappear, or worse could find yourself in serious trouble.
