The mac specs are Core i5 4 GB of ddr3 ram Resolution 1280x800 500 gb HDD The yoga specs are Core i7 8 GB of ddr3 ram Resolution 3200x1800 256 gb SSD Now on paper the yoga is way a head it's just i don't like the yoga's design neither i do like windows 8 i'am using 7. I never bought a mac but now i'am considering it mainly for the design i just love that keyboard , aluminum unibody and that trackpad never tried mac os looks interesting though. Which one is best in terms of performance ? I'am heck confused. Help would be much appreciated. Please don't recommend adding specs or buying anything else. I may upgrade the mac's rams to 8 gb that's it.
