Apple is in dire need of giving their entire lineup a serious kick in the pants, they've been way too focused on iPhones and iPads. The Mac Mini is crap, the Mac Pro is crap, the iMac is middling at best (the new iMac Pro looks reasonably sweet, but the price...), the Macbooks are severely spec-limited, it's just a mess.

They've painted themselves into a "thinness at all costs" sort of corner with the Macbooks, and they've have to go back on that and make them slightly thicker again, if they want to upgrade them. Last time they were backed into a serious corner (G5 PowerPC being completely unsuitable for mobile use and disappointing performance-wise), they took a chance and switched to Intel. They're going to have to mess with some important core design tenets this time.

For the desktop line, a new non-stupid Mac Pro will go a long way. They also need to seriously refresh the Mac Mini, because it's just a piece of junk right now.

Don't forget the upgrade factor. I find it totally ridiculous that you're forced to buy external enclosures for pro-grade equipment instead of just having a nice, toolless access panel for upgrades. I miss the tower Mac Pro, which looked beautiful partly because it looked like a practical, industrial tool designed for easy physical access. Not everything needs to look physically seamless...

The "cheese grater" was a beautiful machine. Sleek, serious, industrial. It looked powerful and cool.

Cool enough that a lot of people still reuse them as PC towers now.

The trash can looks like... A trash can. I'm kinda curious what they'll be going for in the next one, if they've learned something.
