Why would you want it on a resource limited tablet?

1. Apps are full screen with limited chrome already.
2. Separate processes will just eat up limited memory.
3. It won't be any more compatible than microb or any other Mozilla-based browser.
4. It won't be any faster or use less memory because it's "highly stripped down".

I also think there are problems using XUL before we get Gtk+ 2.10 as part of Maemo 4.0.
