I've had a number of Thinkpads in the past and always found them well bolted together and best of all had a nipple.  Also the current tablet, the X41, gets my vote as it has a superb screen and seems pretty sturdy.  Spare a thought then as it seem Lenovo are accelerating the move to drop the IBM name and logo from the PC business it purchased from Big Blue less than two years ago. 

I hope for two, not make that three things.  They remain some of the best made laptops you can buy, you can still get them in black and it's nipples not touchpads.
