lol. i didn't have a case like you but i have one near it....and it acutally in my room.

so i'm sitting there playing on my alienware laptop, then i remember i forgot to plug in the power plug, so here i am yanking the power plug and not looking that it is being twisted along with the power plug of the n900.

so being me, im like wtfux is holding my power plug and decided to keep yanking then "bam bam" and i was like Holly sh.t O_O wth was that"

look down and oh to the hell, my n900 on the damm floor, my house have tiles hard floor and my laptop table is like high above so that is a pretty long drop.

guess wat, same like you, n900 warp in a .99$ rubber casing from ebay and it was unscratched and no dent and still working fine. Gosh i love those cheap china made cases
