Would the changelog not be the first place you've looked for this information? 2.0 Saimaa changelog... and there's other versions including the latest version 2.0.1.x. It was a major OS release with many tweaks visible as well as under the hood. Taking a year is not outside the realm of things. I'll keep it simple. Do I think it was worth 2.5 million dollars? No. But a scalable OS that remedied and perhaps backfilled all of the other issues that 1.0 invariably had... it might prove to be a worthy investment if licensing takes off and manufacturers decide whatever hardware they want to do/use and can do so. But that matters none to us; we want our tablets we paid for, right? Not the investment into making their OS scalable. The argument that it should have been as such from day one is moot. It's there now. But at the expense of the user backed tablets. So back to you. What are you asking exactly? Why did it take a year to produce a major update to Sailfish or are you asking why it cost 2.5 million and the tablets? Or am I misreading what you're inquiring... which is a very possible outcome. And since my words have been taken wrongly in the past; do understand that I'm genuinely curious and wonder what you're inquiring. Thanks in advance.
