>Platform lockin isn't exactly vendor lock-in, but there's a kind of lockin nonetheless. You're going to be dependent to some extent on your platform whatever your platform happens to be.

So you making your own chips off of beach sand or something? /s After a certain point you get ridiculous.

JVM and C/C++ (python and other scripting languages to some degree) are the options if you want cross platform environments.

But on a scale of suckiness:

1) Hardware lock in

2) vendor lock in

3) service lock in

4) OS lock in.

5) app server lock in

6) framework lock in

7) Library lock in

8) programming platform lock in
