When did I ever say I'm not going to use my machine? All I was doing was asking everyone's opinion on a possible redesign and if I should go with a Pro or an Air. I never once mentioned that all I would be doing is looking at it, but yes, that's one reason I'm buying a Mac. If all I wanted was the best bang for my buck, I would've bought a Windows machine years ago.
It doesn't matter what kind of computer you're talking about. It could be one of the latest Lenovo ThinkPads, or the Samsung Series 9.
Haswell has only just been released, and already you're anxious enough that you're looking to a microarchitecture that
may be released in 2Q 2014 (though the latest rumours are putting it at
2015). If you're insistent on this mindset, why not wait then until Skylake in 2016, as someone else mentioned? Or perhaps until 20xx, when Intel adopts quantum computing? You see what we mean here? Why even bother at all?
At the end of the day, you have to ask yourself a question: how much do I really
need a new computer? How much of a productivity boost would I get from a new machine, and would losing that be worth the time spent waiting for something better?
All computers are born to be obsolete. Arguably, they're obsolete almost the minute theyre released - or even sooner, as just as Apple's announced your Mac at WWDC, it's also busy prepping its successor for release in a few months' time (just ask anyone who bought a Quadra 900, or a single-processor 1.8 Ghz Power Mac G5).
If you really want to get truly the best bang for your buck in computing, ultimately, the best choice is no choice at all.
