my x200 takes 20 minutes to POST and the BIOS downgrades fail via both GRUB and windows7. similar experiences litter the lenovo forum. if apple had an issue like this it woulda been frontpaged on every tech site and fixed within a day..
its hard to avoid rebooting because the hardware hardfreezes a couple times a day. also the network slot has a very small whitelist should your card crap out
