Let me explain. Yes, I do like the greater selection of apps. That was a key reason for making the switch. I also like the control I have as a user over a rooted OS, and I like (finally!) having GPS available. Even online banking looks great – I've found homebanking apps that work, and even the web UI is usable (big surprise, since banks are usually one of the last to catch on).
So why is Google so unusable? Perhaps due to several reasons, the biggest ones being:
1. Very limited mobile functionality. If I use my phone as my primary client, I expect to be able to interact with the functions I'd use most often on a desktop. This includes sharing websites, writing email, performing financial transactions, and keeping on top of notifications. So: why doesn't Google reader let me share articles with a comment? Why can't I page through my inbox via ajax loading when I reach the end of the page? Why doesn't Plus allow me to add a link to a website and have the article preview show up? Why can't I mention people in plus using the + sign? Why can't I filter content by circle, feed, category, or group? A mobile user is not necessarily only interested in triaging information, but also in light interactions!
2. Very bad stylesheets for desktop client. So when a website doesn't cooperate, I use a browser with a fake user agent (i.e.pretend to be firefox) to force desktop client loading. This gives me the full functionality that I want. Now, with exception of online forums runnung certain ancient fixed-width stylesheets, most sites render in a readable way: columns don't take more width than my little smartphone screen. Not the case with Google sites. You'd also have thought that the new "fat-finger" design and icons make it easier to click with a touchscreen – nope, it's actually harder. Compare all the zooming and non-clickable "fat-finger" buttons to other sites, where having text links makes the browser recognize it as text and let me click, and have stylesheets that actually render the full functionality in a legible way, and I start to wonder what happened. Fixed width websites are a thing of the past!
3. Location services. I want to leave location services turned off unless I'm actually interested in posting them. For example, I don't particularly want my location to be checked in on Plus constantly, but if sharing a picture of a historical landmark I'd be more inclined to do so. Have you tried starting a Google app with location services off? It crashes half the time. And that is quite annoying.
4. Notifications. I'm missing all of the typical desktopish notifications. Email is fine thanks to IMAP support which lets me use a usable program letting me use an alternate interface, but everything else either marks things pauschal as read and does not pop up a notification, or alerts me on every last uninteresting piece of spam. (Recurring theme: provide better information filters!)
5. UI element positioning. This may seem obvious, but I do expect a button at the bottom of a form. I don't like having to scroll to the top to hit "back" or "post". Most other websites seem to get this right…
I sure hope there's a better answer than "please install opera 2 for browsing Google sites, and use any other browser for the rest of the web". (Amazingly, Google does have a proper stylesheet that renders usably in ancient versions of opera. Cheers to the standard browser on my old Symbian.) No. That's just not good enough.
