I use Windows 7, and I used to use Ubuntu as my main OS for a long time, but I never got around to re-installing it after building my computer.
I have the burned disk right here on my desk, but I'm too lazy to install it.
My Android phone I ordered will arrive with Android 2.3 Gingerbread on Monday.
My current phone uses some Java-based stuff that nobody likes on those stuffty touch screen phones.
