Get the used one. 30% is a lot and 4 months is nothing. Get applecare for it and you are goldenWell, me personally can wait, but the chances are this used iMP then is sold (live in Northern Europe - smaller 2nd hand market, this is the first one I've ever seen for sale). Other ones that may come out may be more used than this one and/or also pricier. I'm now getting it at a 30% discount off listing price after only 4 months usage.
I've been waiting many years for a new mac already, never having been able to settle for either iMac or MBP and then continously waiting for a new type to come out. However, as I'm beginning to grow impatient I had therefore decided to go for the new iMac once released. After it came out with the old design I was thinking about waiting for WWDC to check for an eventual new iMac design, but later figured the chances for this are slim. iMP is normally out of my budget, and I don't expect the Mac Pro to be any cheaper when you include display etc, probably the opposite.
Hence, I found myself with three options:
1. Wait for new iMac design (2020?)
2. Get the new iMac now
Then all of a sudden, the third option; 3. purchase a four months old base model iMac Pro at a 30% discount
As no one can answer option number one, I started this thread to help decide between 2 and 3. I ended up going for option number 3![]()
I missed the discount so yeah, go for it. ;-)
