This is the problem with technology, and especially new technology. . . it advances and improves too rapidly to keep up with. Don't beat yourself up over it, and go with your gut. . . you will be happy you did!
I personally was going to wait, and even contemplated getting a late 2013 iMac due to the sometimes better Nvidia GPU (780m) but instead went with the middle ground retina with m290x, 1tb fusion drive, i5 3.5ghz, and I upgraded the ram myself to 24GB and all in all I have under 2K in the entire setup and couldn't be happier! I encode videos blazing fast with ease with multiple effect filters applied to the timeline and it's just been the most pleasurable experience in my computing history.
DON'T THINK ABOUT IT..BUY IT..it will make you happy for years to come
You are only current with technology the day it's released, but realize they have already started working on the next best thing the day before that.
I agree, but try to time you purchases with new releases. First time I bought an iPhone 3G, I wasn't aware of Apple's release cycle (it was my first Apple product), and I bought it in June. iPhone 3GS was released in July or something
So anyone wanting to buy an iMac 5K for example, should've done it at least a few months ago. Now it makes less sense because new iMacs are definitely coming in 4-5 months, for me, that's close enough, worth the wait so to say.
That being said, I'm always talking from an upgrade perspective. If you already have an older generation, why rush only to regret it a few months down the road? If you don't, or your old iMac died or is dying, sure, buy it today!
I'm also talking from a perspective of a not-so-frequent upgrader. When I buy things I like to use them for at least 4 years, I'm spending a lot of money as it is on devices and what not.
You also have to have a hunch for these things. For example, I wanted to buy a drone so badly, but I wanted a Phantom with a built in 4K camera. I expected them to release it in October, but they only released the DJI Inspire, which was 3 times the price of a Phantom. Normally I'd then settle for Phantom 2, but I just had the hunch that the camera that was in the Inspire was coming sooner or later in Phantom 3. And so it did, it was released last month and I am one of the very proud first owners. It's an amazing piece of hardware, photos and videos are just spectacular. I intend to use it until it breaks, I don't care about Phantom 4 or 5
Wow, I wrote too much...cya!
