Why are you comparing the date of SavaJe's being acquired, with the date of Android being actually released or gaining third party external hardware partners? Apples and apples would be Google's acquisition of Android in 2005 vs. Sun's acquisition of SavaJe's in 2007. And even then, Google acquired the actual devs too, whereas Sun only acquired the code and IP.

And Android is way more a rip off of Palm than SavaJe. All of the interesting things it does (the intent system, the capability based IPC, the battery friendly process lifecycle model, etc.) clearly descend from Palm (which isn't a surprise given that's where Dianne Hackborn cut her teeth).
