Not that it’s a surprise, Apple has unveiled some new iMacs. The new models feature 21.5-inch and 27-inch 16:9 displays along with all-aluminum enclosures. The new widescreen IPS panels are LED-backlit and provide 178-degree viewing angles.

The 21.5-inch iMac sports a 1,920 x 1,080 resolution, while the 27-inch version leaves that in the dust with 2,560 x 1,440. Ports are the same as the previous model, but they’ve added an SD card slot and video-in on the 27-incher. The wireless keyboard is now standard along with the new Magic Mouse.

The Holiday season is upon us, so it makes sense that Apple would be ready to offer its 2009 Mac product line. According to Apple Insider, it could happen as early as this month. We’re talking a new line of iMacs with more stylish enclosures and some other added features not previously available.

Apparently, the new all-in-one, dual-core desktops were finalized earlier in September and have been rolling off the product lines for about two weeks. A thinner chassis and lower prices are expected. We may even see Blu-Ray.

Add this one to the ever growing pantheon of Apple rumors. PCPerspective has reason to believe that Apple is preparing a 24″ iMac. They say that we will get a set of four new iMac computers announced this week. Two 20″ iMacs with an NVIDIA integrated-GPU chipset based on the MCP79 design (the same used in the most recent MacBook and MacBook Pro notebooks) and one of those will include the mobility GeForce 9600-series discrete GPU as well. This integrated + discrete graphics solution is basically identical the setup the new 15″ MacBook Pro includes.

If you buy into the hype, the 24″ iMacs will have the same integrated chipset but both of these will include discrete graphics solutions. The lower-end 24″ model will use the same mobility 9600 series that the MacBook Pro uses and the higher-end model will use a slightly faster GeForce 9800M solution. That would make the new 24″ iMac a useful gaming machine.

For many the iMac is not just a computer - it is also a piece of art. To that end a company by the name of Chromac recently unveiled a line of tasteful enclosures to up that artsy look. These iColor enclosures are priced at around $500 starting.

The Chromac iColors come in 11 colors and let iMac owners customize their computers with “high end finishes and materials commonly found in a Gulfstream jet or Rolls Royce.” These designer upgrade choices include chrome, 24K gold, platinum and lime green. Chromac is also known for designing customized aluminum cases for iMacs as well.

If you happen to be one of the lucky bunch bringing home a fancy new aluminum framed iMac today you will also have the opportunity to apply your first software update, all in the same week. Only one day after Steve Jobs announced the release of the new iMacs Apple put out its first Software Update 1.0 with a very short and to-the-point message:

“This update provides important bug fixes and is recommended for 20-inch and 24-inch iMac models with 2.0, 2.4, or 2.8GHz processors.”

It’s not clear exactly what the 5.1MB download addresses other than it has today’s release date and that it requires Mac OS X 10.4.10 and a mid-2007 iMac. Along with this, as usual, is an update to the dual-boot software Boot Camp 1.4. Since we’re on the topic of Apple software updates, …

Today Steve Jobs announced Apple’s new iMacs at the companies summer press conference. The announcement came as no surprise to most as rumors of the new iMacs and their features have been plentiful over the past weeks.

Jobs made heavy reference to the construction materials of aluminum and glass with the new iMacs, talking of its “elegant” look, the fact that the glass is scratch resistance and how both materials are recycle-friendly. The new iMacs will come three models of 20-inch and 24-inch glossy frames.

All three models feature USB 2.0, Firewire, 8x SuperDrive, and an iSight camera as you might expect. They also house aCore 2 Duo processor, ATI Radeon HD Pro graphics card, 802.11n, Bluetooth 2.0 and 1GB of RAM.

Pricing runs from $1,199 for the 20-inch model with a 2.0GHz processor, 250GB …

Is this a picture of a new keyboard from Apple that will come with the new iMac? The folks over at Engadget received a tip and this looks like it could be legit. It has the same brushed aluminum finish as we are expecting with the new iMac and it’s certainly as thin as we would like to see as one of the photos holds up a ruler showing the keys sticking up to just slightly over one millimeter.

The rumor came from a message board where someone had a number of these supposed new iMac keyboards for sale for just over $150 each. Since then most of the pictures have been taken down.

As Engadget pointed out, there isn’t an Apple logo on the command key which seems odd, but if this isn’t the real …

More rumors are being fuled across the blogosphere from ThinkSecret with additional information on the new iMacs from Apple. It looks like the release of these new units are on track for an August launch and will be sporting a brushed aluminum enclosure instead of the shiny white plastic. Although the frame overall will be very similar to the current iMac it will be thinned down to only 2 inches thick. The bottom space below the screen will be shorter too, giving more screen compared to overall size on the enclosure.

The real anticipation for these Macs comes from the Santa Rosa chipset that’s expected to come along inside them maxing out a 2.4GHz. They also are rumored to come in sizes of only 20″ and 24″, and the line of smaller 17″ screens …
