apple released a new mac mini i think this week, whats the difference from the one that cost 699 to the one that now cost 599 besides the price? does mac still sell the ones that were 699? i dont understand what they did with the mini now
So the differences between the new baseline mini and the old mini are:
New Processor, it now contains an Intel i5 which should give it a pretty decent performs boost from the core 2 duo.
Bigger hard disk drive at 500 GB compared to the old 320 GB (but still both at the speed of 5400rpm)
No more DVD drive
No more dedicated graphics card the new mini uses the HD 3000 IGP. From most reviews I have seen it is better at doing video but slightly worse at doing games, overall though there is not much difference between this and the previous mini graphics.
Now to answer you second question, yes there is also a new mini priced at the same value as the old one. For your extra money you get a slightly faster processor (200mhz), an extra 2 GB RAM memory and a dedicated video card the AMD Radeon HD 6630M with 256 MB GDDR5.
Which one you want will depend on what you want to use it for
Personally I detest wireless keyboards, as they always seem to run out of power just when I need them most.
I think the track-pad is a cool idea as it will allow you to get the most out of Lion.
