I could agree with this thread %100 if it was in ipad/iphone ram or other similar topics. However mac mini is choice of many semi-pro people and developers who develop for apple and make them money.
That is part of the problem. Apple doesn't have a mid range desktop. If there was an xMac with 4 and 6 cores, drive bays, and GPUs, most of the people wanting more from the mini wouldn't even care the mini didn't have them.
On top of this, haswell requires a separate motherboard for quad options. There are no quad core MBP 13, there are no dual core MBP 15, apple only makes one mobo per model. So Apple should make two mobos for a cheaper model?
On top of this are huge delays from Intel. Apple could have delayed longer on a refresh, but was already getting pressured for action (including by us).
I'm hoping to pick up a refurb, but I am clearly done with the mini lineup if this is a permanent step for Apple, which I highly expect it is. I use several minis as servers and the ability to swap drives, improve RAM etc is important to me.
Minis are based on MacBooks. The last one was based on the last MBP 13. This one is based on the MBA. The MBA has PCI SSD and soldered ram so the new mini has PCI SSD and soldered ram. The next mini is likely to be redesigned. If it's still based on the MBA, it will likely remain inflexible.
