I have a early 2011 2.7GHz i7 13" with 8GB RAM and 512HDD. I'm considering upgrading this machine to the 840 evo for around $300. I'm not sure whether it's worth upgrading or just spending $1,500 for a new MBP with retina display and thinner body and lighter weight… The issue isn't the money - $1,500 means nothing to me, but the need of a laptop. If I were to buy a new laptop, it seems like too much hassle to sell this one off or pass it to someone. On the other hand, I could just buy the SSD, swap out the HDD, and go about it. Kind of confused as to which makes more sense. How much life would this machine have left anyways? I generally push it to its limits but it hasn't let me down once. Bought it when it came out. Assuming I can make it go for another 3-4 years, do you recommend upgrading the SSD or trashing the machine? Also, I have AppleCare on this machine until June 2014. Does upgrading void warranty? Lastly, if I upgrade to SSD and swap out the HDD, how would I go about installing OS X and so forth? I have a time machine backup drive.
