Hey all, I'm currently a rising senior in high school and I have been saving up to purchase a 15" rMBP before leaving for college. I was planning on buying the Broadwell version later this year, but apparently now the chips have been delayed and won't ship until summer of 2015. Now, since I'm going to be attending a 4-year university followed by four years of med school, I don't plan on upgrading for a while. I assume the Broadwell will be slightly more future proof, but what mainly draws me in is the promise of much better graphics (I'd be getting the base 15" with an iGPU only) and better battery life. How much of an improvement would the Broadwell chips be in these fields? My other concern is that the Broadwell chips won't be available until around June or July of next year. Does this mean that the new rMBPs will be released in time for me to get one by early August, or will Apple need a couple of months to implement the new chips (in which case it probably won't be released in time for me to buy one)? Thanks!
