My main point was that the ruggedness and superior build quality of Thinkpads used to have limited drawbacks: they were at worst 10 to 20% heavier than alternatives (and sometimes even lighter, like the 560 around 1995). Not so anymore, especially in the smaller and lighter models: the X200 (and X300) are 120% (and 70%) heavier than a R500. That's why I finally reassessed my longstanding commitments to Thinkpads. But you are right to point that it may be less of an issue for the T series than for the X series: I would probably have stuck to Thinkpads had I been looking for a 15+ inches screen.
