So I finally have an i7. I previously had 3 i5's which each had a problem. AppleCare was kind enough to upgrade me for free to the i7. I have spent ~3 weeks with an i5 until today when I got the i7. I thought I would write a few words about what I have noticed and experienced so far. While the jump in Geekbench score between the i5 and i7 is obvious (~7600 to ~9800 with 8GB ram), the subtler things are what I have really noticed. The i7 still boots up quickly, under 30 seconds just like the i5. However everything just seems snappier on an every day use. I have been using the i7 for the past 7-8hrs and I noticed a difference in the first hour. I decided to do a clean install of OSX (I also did this on all 3 of the i5's). On the i5's it would take me just under 30 minutes to do a full install (without the printer drivers and languages being installed). Today on the i7, I kid you not, it finished it under 12 minutes from start to finish. I really thought there must have been an error in the process or something wrong happened because I was not expecting it to be done that quickly. But sure enough, just under 12 minutes for a full install. I also notice that the system idles a lot "smoother" on the i7 vs. the i5. On the i5 just being on the internet or the forum the processor would "idle" around the low 90's%. Now with the i7 under the same circumstances I am getting around 97-97% idle consistently. While installing iWorks and iLife I was also on google chat and the CPU was still at 95-96% idle. Just amazing. One thing I have noticed is that the i7 tends to idle at a few degrees celsius warmer (~3-5) under the same conditions as the i5. Nothing really worth worrying about, however I notice the temps are just a bit warmer. Overall, the i7 is amazing. While the i5 is a great machine, the i7 is definitely the hands down winner. If any of you are still trying to decide between the i5 and i7, while I understand that money is tight, I highly highly highly recommend waiting a little bit longer to save up that extra $180-200 for the i7. It is more than worth it and you will be much happier. So the take home message is that the i7 is amazing and is definitely a noticeable difference over the i5. I just want to add that I realize there is no scientific data from me and that this is just anecdotal evidence. I just hope that this was useful for you guys.
