Hi there
Wipe Linux off it before it goes back otherwise some "Clever Dick" in the service dept will try and say you've "Voided the Warranty".
Incidentally -- slightly OT but relevant for any Internet or Physical store purchase. If you pay with a CREDIT CARD (note not a Debit or instant money type card or AMEX which is a "Charge card" - legally works as a Credit card but isn't actually a Credit card) then whether there is a warranty or not you have the right to a refund if the goods are not of "merchantable quality - I.e they must be what you paid for and perform the function stated in the specs -- if you can't get a refund from the VENDOR (doesn't have to be the manufacturer) then the CARD ISSUER has to refund your money or get you a new product AT THEIR expense.
This is how it works in the UK -- other European countries it's similar as it's an EU directive. I'm amazed how many "Locals" don't know even the basis of Consumer law in their own countries - It doesn't cost anything to do a tiny bit of research to know and understand your basic rights - especially in these days where "rip offs" seem to be the norm.
Can I claim on my credit card when something goes wrong? - Which? Consumer Rights
I got a Brand new SAMSUNG S4 phone FREE this way -- I paid for an unlocked phone -- when I received it they sent me a Locked phone and said logon to the Internet and you'll get the code to unlock it (at an extra cost of 20 EUR !!). I refused - I received a different product from what I'd ordered-- they said well that's it -- we aren't refunding your money -- so I had a go with "Sharkley Card" (Barclays!!) and got a brand new phone FREE - they didn't want the old one back so I paid 20 EUR to unlock it and sold it -- so a nice S4 Galaxy for 20 EUR.
(This type of law applies in the EU and EEA -includes Norway, Iceland, Switzerland etc. Probably in the US you'll have similar state laws governing this type of stuff --not sure about 'OZ or Asia though).
