I put in a vote for Java ME. The reason is:

- On any computer equipped with a browser (that includes Java) I can reach my workstation.
- The N900 has a great browser which works wonderful.
- It just lacks the Java support needed.

To do what? Use Secure Global Desktop (SGD) to reach my workstation (safely placed in a datacenter) and get work done.

For more on SGD: Wiki page 1.
For the type of Java support needed: Wiki page 2.

I really hope Java support will arrive soon. It would finish the "computer in your pocket".
