I believe I just got very lucky! My history, had a sp1 that dog knocled off chair and screen broke, bought a s3 which I am currently using but it just doesn't seem fast enough - so I started cruising ebay. Last night I bought a sp3 i5 8mb ram and 256 gb ssd for $280, guaranteed working and with a power supply! A seller who deals mainly with server parts (high end network boards, etc) had 8 of them and sold out very quckly. I also bought a 1 year sq trade warranty for $38 with it. My plan is to sell my s3, kb and pen for at least the $280 I paid! Will by sp1 or s3 keyboard work on it? When I get this anything I should check on it? LOL, or should I sell it for $4-500!!!
