First and foremost, I am new to this forum. I could use some help when it comes to choosing these 2 notebooks. Based on my research, it appears that the 13 inch Macbook Air(Haswell) suffers from wifi connection issues, is this a software or hardware problem? To date, it appears that this problem has not been solved by apple. Next, does 13 inch Macbook Pro retina(Haswell) suffers image retention problem? This will be my first Mac and I plan on using it for coding. Please advise and thank you .
