Hi, after viewing the MacRumors buyers guide, I see that the recommendation is to not buy a MBP until the new one is released. However, it seems that the next generation of MBP will not be arriving until June, and I need the computer for a class before that. How big of a difference is there in between generations? If it is only a minor processor upgrade and slight videocard change, I will probably not bother, but if it very major I might be able to hold out. Also, I read something about the next generation being all retinas - If I do not want a retina MBP, should I not wait? Sorry if this is in the wrong place, I couldn't find a more appropriate forum.
