"First off I thought I’d ask Amazon what the
correct procedure is for requesting a refund. So I sent them an
email from my Amazon account last night (at about 10:00pm):
"...I should point out that the chap at Amazon also suggested
that I check with Asus that removing the software might invalidate
my warranty on the device. I have searched on Google and on
Asus’ website and read the Warranty card that comes with the
device. I couldn’t see anything that would indicate my
warranty would be void if I change the software. I have mailed Asus
to try and confirm it will be OK. [Update: I've just had a message
back from Asus saying my Warranty will fine. They don't "support"
other operating systems but I can understand that completely]
Frankly, it would be a pretty USELESS warranty for a computer if it
became void by installing new software. But I am not a lawyer so
don’t take my word for this and YMMV."
