A current generation processor would be nice.
Since the next jump in computers without an all-in-one configuration is the expensive Mac Pro, I'd like to see a Mac Mini, a Mac Mini Server, and a Mac Mini Extreme. Extreme using more the i5 with more robust graphics and a 500gb hard drive.
No middle ground with Apple. If you don't want an Imac, you may choose between a Mini with a processor that is 3 years old, or a Pro that's over two grand. Shameful.
4GB of ram standard, 8 optional
SSD
eSata port
Much better cooling!!! Gaming really gets the Mini very hot so I use an external fan to help cool the case.
😱
2GB of ram and the slow hdd are totally crippling the new Mini. Many people say it is supposed to be faster than my old PowerMac dual 2.7 LC. The fact is my old PowerMac was often faster than my new Mini until I upgraded the Mini's ram and hdd. It is now the machine it should have been, straight from Apple in the first place, without me having to perform surgery to swap the hdd.
the esata would give you real connect-ability. the unit would sell. make the base model have 80 gb flash for the hdd and 4gb ram. user can add an esata enclosure and have a real ht setup.

PS.Technically speaking the Core 2 Duo in these Macbooks and Minis is not the same one that apple had 3 years ago. Those ran on a 667 buss. These current ones are 1066 buss. The buss speed makes a lot of difference in how fast your data flies around inside! A 2.4ghz core 2 duo from 3 years ago get buried by current chips of the same speed.
