I guess it depends who "we" are. The average person dont need a new computer, I agree. My mom is still using my old self-assembled desktop from 2008-ish and is perfectly happy with it. However for those of us that use our computers 8 hours+ every day, I think it makes good sense to upgrade to the newest hardware every 2-3 years. I just assembled a computer from new parts myself, and its nice now to have a fully encrypted workstation, with zero performance hit. Q87 motherboard with TPM(asus q87m-e) + UEFI bios + UEFI GOP Compliant videocard(EVGA GeForce GTX 770) + M500 SSD + Bitlocker + Win2012R2(or Win8.1) means you can enable the builtin hardware encryption of the M500 SSDs. It gives me a certain peace of mind to know that a burglar wont be able to grab my personal files and source code if my computer was ever stolen. I also imagine the TPM+Secure boot combo will make it harder for a rootkit to go unnoticed. Not to mention the lower idle power usage resulting from the 22nm haswell and 32nm lynx chipset. My friends at work seems to think I'm crazy for replacing a 2 year old computer :) Although as I pointed out to one of them, he spent more than twice as much on a new mountain bike, and I'm sure i spend alot more time on my computer than he does on his mountain bike ;)
