I don't know about the extended warranty but MS's standard warranty is a rip off. The way it works is if you buy a Surface you are supposed to be covered by the standard warranty for a year. Assume your Surface stops working after two months and you return it for it for repair. MS carefully scrutinizes the device looking for any scratches and if scratches are found on the device then your warranty is VOIDED. The only way to then get a repair is to pay MS $300.00 for out of warranty coverage. Item (iv) below is the relevant clause: Warranty Exclusions (a) Microsoft is not responsible and this warranty does not apply if Your Microsoft Hardware or Accessory is: i. damaged by use with products not sold or licensed by Microsoft; ii. opened, modified, or tampered with (including, for example, any attempt to defeat or circumvent any Microsoft technical limitation or security mechanism, etc.), or its serial number is altered or removed; iii. damaged by any external cause (including, for example, by being dropped, exposed to liquid, used with inadequate ventilation, etc., or failure to follow instructions in the instruction manual); iv. scratched, dented, etc. or shows other cosmetic damage; or v. repaired by anyone other than Microsoft or an authorized retailer. This is certainly not the policy with Apple and the iPad. Hopefully Best Buy has a better warranty policy. MS does not communicate this when you purchase the device you have to go to there web site to find out about the policy.
