Ipod Nano damage complaints

Having posted on the coolness of the iPod Nano earlier this month, there seems to be all lot of people moaning and whinging about how their screens cracked from being in their pockets and how easily scratchable the screen is . When you buy something for $249 then spend another $20 on a skin to protect it, preferably before you use it ! Then you read something like this http://arstechnica.com/reviews/hardware/nano.ars/3 and you wonder what the fuck people are complaining about !
