That doesn't sound like a good habit to have in this industry, things change and software evolves. Android's first few versions sucked..a lot for instance. Heck, most the of the early versions of OSS suck. Are you saying there should be a constant rate of change? If you're a programmer, you should really try coding on Visual Studio 2012/.NET/F# and C#. It's a breeze. Very smooth compared to Eclipse.
