Hi everybody! I'm currently using a Lenovo Y570 that has i7 2630QM, Nvidia GT555, 8GB RAM, and 750GB hdd (5400 rpm). I'm planning to buy a new rMBP 15" base model but I have some doubts and questions. Almost everyone complain about IR issue on LG screens. There are many complaints about laggy behavior in many cases such as typing and web browsing. This will be my first Mac and I don't wanna face problems with a laptop that I pay over 2000$. You can say "Don't buy it then" but I'm a recently graduated computer engineer and many of my friends say macs have many advantages over classic Windows machines. I want to experince the rMBP. I bought my current laptop 1.5 years ago and now I'm not sure whether I should buy a mac or not. Should I wait for the next release/upgrade or just buy it now? Btw this wait process is not for a newer chip (haswell) etc but for the current problems of this machine to be resolved. Thank you.
