You have same trouble as me. I am student, I also do Android Studio and
Unity. I love Unity, nut yes, is proprietary. I don't know how good is Godot,
but I think that is the best alternative possible to Unity.
I have T400 but did not tested, greatest laptop you can buy but shittiest
screen ever, it is almost painful to see at it, colors are fully washed out.
And I have T400 led and ccfl versions.
I think that T400 can be enough for game developement, 8gb of ddr3 ram are
great, but old core2duo, if you buy T400, take T9600, this one costs about
20€.
