I lucked out, and got a new Razer Blade through a pricing error from Amazon. In Canadian dollars, I only paid $2750 tax in for a nRB with 1TB of SSD, 6GB GPU, and 16GB of RAM. As a Apple user for the past 10 years; I have used 2011 MBP until the nRB. Now with the new rMBP (maybe) on the horizon, I'm tempted to remain in the apple universe. From what I can tell, these would be the major differences - and I'm trying to see if it justifies the cost different and the transition from MAC OS to Windows. Pros (Buy rMBP, sell nRB) better specs (2.9/3.8 vs 2.8/3.8) for CPU, better res (2880x1800 vs 1920x1080), has facetime/imessage/apps such as photos for management and spark/omnifocus which don't exist in Windows universe. Cons (keep nRB, don't buy rMBP) rMBP cost (if it stays the same as current price) will cost me $4.9k after tax with the same specs as what I have through nRB. thats over $2k price difference. In addition, if they don't update GPU - I'm stuck with the older/slower GPU @4GB. My main reason for the top of the line system is playing my favorite vice - FM17 which is extremely intense on CPU/GPU, photos management, video editing (my job) etc. What would you folks do?
