> Worst of all, there are no frequent updates (if any), no autoupdate either.
Is a little odd. Didn't you install the L developer preview by manually downloading the ROM from here: https://developer.android.com/preview/setup-sdk.html and then flashing it yourself? Then you're strangely shocked there isn't a consumer-orientated auto-updater?
I can absolutely see that criticism if the auto-updater didn't exist, wasn't working, or there were no updates upon the retail release of L. For a developer preview you personally installed knowing full well it was a developer preview that criticism is hard to take at all seriously.
Google never promised updates, never promised stability, it's not a beta, it's not a GM, it's not even alpha. It's simply a preview. You get what they say you get. Don't set iOS's standards on Android, they're completely different products, with completely different cultures, release cycles, everything.
There are a lot of products, Google and otherwise, that go straight to release without any prereleases. If anything Android has has a very strict record of that, so I think your expectations of much more from them on such a large release like L is simply unfounded.
It's more the terrible quality of your posting. You've been given reasonable answers but instead you respond with demands you have no position to be making.
Your approach sounds like a crappy manager who insists that because you sent something to QA, that means it's shippable RIGHT NOW LET'S GO ALREADY THE SHAREHOLDERS ARE DEMANDING IT
I haven't had a single problem with it, I've been using it for months and love it.
On what hardware? I did not notice a difference on my Moto X. My Moto X is in repair now and in the meanwhile I have been using a Moto G. On that, I definitely notice a difference - app starting and multitasking is a whole lot faster with ART.
