This post reminds me of the Incandescent light bulb vs LED bruhaha. Personally, I've switched to all LEDs. No big deal. Life goes on and on and on.
Invalid analogy. I didn't switch from incandescents to CFLs until good quality CFLs came out (even then, they are unsuitable for use outdoors—they fire too slowly and are dim initially when temperatures are low—I use halogens there). Even then, there are only a couple of brands of CFLs I'll use because the others don't measure up. I have only two fixtures in my house converted to LEDs because the LEDs I've tired or have looked at are too long to fit in the fixture without looking uglier than even CFLS, are too directional, or put out light with a harsh bright spot. Unless an LED is an overall improvement over the CFL I'm using now in economy (cost of use combined with length of life and initial purchase price), quality of light produced (correct color temperature), can be used in totally enclosed fixtures (read the fine print on the packages; most LEDs can't be used in totally enclosed fixtures), and not look ugly in a fixture (the aforementioned length factor), I refuse to use it.
The same is true of Win 7. I will not replace it until it is an overall benefit for me to do so. I didn't upgrade from XP to Vista and, when it first came out, Win 7 because I would have had to replace a computer (which would only run 32bit Win 7 without Aero), a laser printer, a flatbed scanner, and one very expensive piece of software, all of which were meeting my needs at the time. I eventually replaced the printer due to the difficulty of getting consumables, the scanner because it was finally wearing out, a Win 7 upgrade came out for the aforementioned software, and the computer was no longer meeting my needs, plus XP was reaching EOL in another year. It wasn't until then that upgrading from XP made sense.
When I was planning to build my desktop machine, I had to choose between Win 7 (which I was already reasonably familiar with because I had been using it on the notebook I bought the previous summer) and Win 8.0, which was just coming out at the time. I had no trouble transitioning from XP to Win 7; in fact, I was pleasantly shocked at how easy it was when I first tired it out before buying my notebook. Not so with Win 8. Since I'm leery of buying into new technology until it's been proven, I waited until Win 8 came out and could try it. I found it difficult to impossible without direction and saw no real benefit with most of the changes such as the klunky, horizontally oriented tiles instead of menu lists (I don't like icons either but, at least, Win 7 lets me eliminate or minimize them) hidden charms that would pop up at in opportune times, etc. Going with Win 8 for my desktop would have also meant having to be familiar with two OSes since I saw no benefit whatsoever with upgrading (actually, downgrading, in my not so humble opinion) my notebook from Win 7 to Win 8. Add to that I feel Win 8 is ugly as sin (and that doesn't include the lack of Aeroglass since I also feel it's ugly and have it turned off in Win 7). Since Win 7 was going to be around for seven more years at the time, a long time in terms of computer life, and I didn't like the direction M$ was going (mobile, cloud, and subscription computing), it made much more sense for me to commit to Win 7. After seeing and actually using Win 8.1 for about a week, I do not regret that decision.
