Here's one report of someone who had an experience with U100 in an

Personally, I avoid like the plague laptop computers where I can't
replace the storage devices (or upgrade memory, etc.) without voiding
the warrantee....

I generally order laptops without the flash device, and carefully
select for high quality flash devices.  Otherwise, you end up paying
too much for what is generally shoddy equipment....
