The new iMacs boast LED-backlit 21.5- and 27-inch widescreen displays in an edge-to-edge glass design and all aluminum enclosure. They’re available with Intel (INTC) Core 2 Duo processors starting at 3.06 GHz, and Core i5 and i7 quad-core processors for even better performance. The low-end model is priced at $1,199, the same as the past generation, but its high-end sibling is now $200 cheaper, at $1,999.

The new MacBook features an 13.3-inch LED backlit display, a multitouch trackpad, and a $999 price tag. Though still housed in white polycarbonate plastic, it features an updated unibody design borrowed from the MacBook Pro.

The successor to the Mighty Mouse, Magic Mouse, eliminates mechanical buttons, instead, employing the same multitouch surface found on the iPhone, iPod touch, and Mac notebook trackpads, allowing users to navigate their desktops with simple gesture commands.

Accompanying the Magic Mouse is a a new Apple Remote. It’s got a new design and is, predictably, housed in aluminum.

Finally, Apple (AAPL) also updated the Mac mini. While its design is largely identical to that of its predecessor, it offers far more storage. Starting at $599, the entry-level Mac mini features a faster 2.26 GHz Intel Core 2 Duo processor and 2GB of DDR3 1066 MHz memory, a 160GB hard drive, five USB 2.0 ports, FireWire 800, Nvidia GeForce 9400M integrated graphics and a SuperDrive.

There’s also a new $999 Mac mini that’s specially configured with a Mac OS X Snow Leopard Server. It’s outfitted with two 500GB hard drives for a total of 1TB of server storage.

Quite a refresh and one analysts are already crowing about. In a bulletin released after the announcement, Piper Jaffray’s Gene Munster said Apple’s new machines will undoubtedly improve the company’s prospects for the December quarter.

“We expect the new iMacs, and to a lesser degree the new Mac minis, to help the desktop category rebound in the Dec. quarter,” Munster wrote. “In other words, the headwind that existed in the Sept. quarter due to aging Mac desktops has now turned into a tailwind for Mac units in the Dec. quarter….Bottom Line: Street Mac numbers may also be conservative if positive trends continue coupled with new Macs in the quarter.”

The new machine is largely as predicted. It boasts Apple’s new unibody chassis and a glass touch trackpad. At 6.6 pounds, it’s the world’s lightest notebook. It has a hi-res backlit display. “The best display we’ve ever shipped in a notebook,” says Schiller, with a 60 percent greater color gamut than other machines.

The new Pro has the same glossy screen as its brethren, but thankfully, it’s available with a $50 anti-glare option as well.

Finally, it incorporates a new battery pack that boasts an eight-hour charge life and 1000 recharges, three times the industry standard. It’s not the zinc battery that some observers were expecting, but very innovative nonetheless. There’s a chip in the battery that intelligently monitors an “adaptive charge,” whatever that means. Bottom line: three hours more battery life than previous machines. According to Apple (AAPL), the battery should last five years, which will result in fewer batteries and landfills and makes this 17-inch model a greener machine.

The new Pro 17-inch MacBook starts at $2799 and will ship at the end of the month.

Also: A new LED display, 24-inch built-in iSight, built-in speakers and MagSafe.

Cost: $899; available in November.

As for the existing standard white plastic MacBook model, Apple (AAPL) is dropping the price to $999, according to Steve Jobs.

Back to the refreshed line, MacBook users have been asking for “a metal enclosure, faster graphics, and LED display,” Jobs explains. “We’re giving it to them.”

Similar features as the new Pro: unibody enclosure, glass trackpad, faster graphics Nvidia 9400 graphics chip and a five-time increase in graphics performance. The new display is designed with laptops in mind.

And continuing a theme at this event, the new MacBook is environmentally friendly. It has also been awarded the EPA EPEAT designation.

The new metal 13.3-inch MacBook sells for $1,299. The $1,599 model buys a faster processor.
