+1 for x230. I can't really comment on how I was handling mine vs what the OP does to their laptops.. but mine held up fine for ~4.5 years in near-daily use (work machine, incl. some personal and travel use) with just a little crack at the side. After 4.5 years I had to replace the screen though. And I'm on the third battery now, so overall "replacement parts" cost was like 80 (screen) + 1x 70 (big battery) + 1x 40 (small battery).
