>You think that you need your computers up to date because you are a geek and you must stay up to date to remain competent.
Nah, I think I need a new computer because the $900 one I have (4 core haswell oc to 4.6 Ghz, 16 GB ram, 3 drives) and the $600 server I have (4 core Sandy, xeon, 32 GB ram, 5 drives), take anywhere between 2 days and 3 weeks to finish the tasks I throw at them regularly.
Between the MLC SSDs, tons of RAM, ton of CPU power, for $1500, I wouldn't even look at MBP from the current batch, let alone one from the last one.
I am a geek, I am competent, and I am fully planning on two new computers this year. Just waiting to see how Zen turns out.
64GB Ram / ea. 1 GB SSDs, probably on ZFS, 8 cores / 16 threads (to stay in the cheap consumer range). This will probably be doable for under $2k.
So, as a geek, this is what I do to remain competent, hardware wise.
TLDR: You can't just assume that because you don't need a more powerful hardware for blogging or what have you, that the rest of us also don't need one.
I can't manage with less, because life is short.
