From what I understand about differences between Xi and Xe is that Xi is the creative one and Xe is all about executing it outside. It means that Ti creates order and Te just goes "wild". I think my Ti is rather bad. T types probably have better access of both Ti and Te. It would be nice to have first hand experience of SEE's Ti (probably creates rather chaotic life). I'm very interested of scanning with Ne and executing with Te so I usually fare well with computers unless it becomes very complicated.
I score quite low on systematizing quotient http://personality-testing.info/tests/EQSQ.php
