I've only ever used Thinkpads (from T20 to T61) and now am on MBP. The TPs are definitely built sturdier. I used to carry them in a very flimsy backpack and all of the TPs weathered that fine. That being said, after I bought my MBP, I bought a nice backpack to protect it. And obviously, the difference is in the software. I think the major diff between a TP and MBP is like the diff between a Jeep Wrangler and a Porsche. Just depends on what you need it for and your OS preferences.
