is it logical for me to get warranty? here in canada, an 8gb 2g ipod touch is worth 300 dollars on the spot (with tax already included).. and i have a perfect 300 lined up for it. I dont want to spend anymore on it. 1) how much is warranty? 2) what does it cover?, say i turn it on and i find a problem..like that it freezes, do i need warranty for that? or can i just return it for another w/ the need for warranty? 3) say i dont buy warranty. and my ipod has a problem/broke. how much does it cost to repair it?
