The Apple iMac just went super thin, but there’s more to know about the Cupertino company’s all-in-one computer solution than that. Thinking of getting one? Want to know how out of date your computer is now? Here is the new Apple iMac release date and all the details you’ll need.

iMac screen: 21.5-inch or 27-inch
You’ve got two choices. You can have the big screen or the really freakin’ big screen. Our advice would be to go for the latter. You know, if you’re going to play the all-in-one game, you may as well enjoy yourself.

The 21.5-inch iMac brings you a 1920 x 1080 pixel resolution, LED-backed and with IPS technology, and that makes for an unimpressive sounding pixel density of around 102ppi. The 27-inch iMac, on the other hand, is a bump up to 2560 x 1440 but, do your maths and it doesn’t come out much more Retina-like at 109ppi. Still, big screens either way.

iMac processor: 2.7/2.9/3.1/3.2/3.4GHz, all quad-core Intel Core i5/7
While the headlines are that the four iMac models come with the a choice of quad-core Intel Core i5 CPUs, read the small print and you’ll see that you can spec all the way up to a 3.4GHz Intel Core i7 if that’s what you really want. Likewise, the more impressive of the two 21.5-inch iMacs can come with 3.1GHz quad-core Intel Core i7 chips if you’re willing to pay.

iMac memory: 8/16/32GB
The standard amount of RAM is two modules of 4GB in each, all the way up to a total of 8GB of memory. Should you wish though - and why not, you devil - you can max out the 21.5-inch iMacs to 16GB and the 27-inch machines all the way to 32GB. Have fun with that.

iMac Storage: 1TB or 1TB/3TB Fusion Drive
Fusion Drive is Apple’s own way of describing the hybrid storage options that the likes of Acer and HP having been using with Ultrabooks up until now. You can choose to have just a plain old 1TB HDD with your iMac or you can opt to have it boosted with a flash storage section to house your OS and all the apps that come pre-installed with it.

Any third-party bits and pieces and any media goes on the HDD. The idea is that you get faster boot, faster core operation and faster read/write speeds. If you go for the 27-inch iMac, you can work that up to 3TB of HDD with 768GB of flash.

iMac graphics: Nvidia GeForce GT/GTX
Gamers will be pleased to note that it’s possible to configure the 27-inch iMacs with a 2GB GPU in the shape of the GeForce GTX 680MX, but even the standard top-end 1GB card should easily be enough for most of your fun. The 21.5-inch iMacs are still perfectly respectable with their GeForce GT cards with 512MB of memory to burn.

iMac connectivity: USB 3.0/Thunderbolt etc
The iMac comes with 4 x USB 3.0 ports all lined up alongside a pair of Thunderbolt sockets. On top of that, of course, is an SDXC card, your Mini DisplayPort that supports DVI and VGA and one’s bog standard Ethernet connection.

On top of the hard lines, there’s also n-rated Wi-Fi and Bluetooth 4.0.

iMac webcam: FaceTime HD camera
Like pretty much all of the Apple products these days, the iMacs come replete with the FaceTime HD camera front and centre with respect to your visage.

iMac sound
The iMac comes with stereo speakers - as one would expect - and dual microphones for better sound pick up without having to use a headset.

iMac dimensions: Big & Heavy
For what it’s worth, the 21.5-inch iMac weighs 5.68kg and measures 45 x 52.8 x 17.5cm with the stand. The 27-inch model is a whopping 9.54kg and is 51.6 x 65 x 20.3cm. Probably not worth trying to fit them in your backpack.

iMac power saving
Perhaps the idea of power management isn’t such an issue for some people, given that your iMac is going to be plugged into the mains at all times. Then again, anyone looking to save the pennies on their energy bills and concerned about green issues might like to know that the new iMac, we’re told, uses 50 per cent less power when in idle mode. Given that many people never even turn their iMacs off, that seems like a reasonable saving.

iMac price: £1,099-£1,699
Apple likes to keep it fairly simple with the number of products in each line. With the iMacs, it’s no different - two screen sizes, two spec levels. The bottom end 21.5-incher with the 2.7GHz CPU comes in at £1,099 and the step up at that size is £1,249. For the 27-inch iMacs, it’s £1,499 for the “more basic” model and £1,699 for the deluxe, top-end version.

Any of the off-menu-type 32GB RAM and 2GB GPU bumps come as extra. A lot extra.

iMac release date:
Those after the 21.5-inch Apple iMac aren't going to have to wait too long. You'll be able to get your hands on yours in November 2012. If you're saving your cash for the 27-inch model, then you'll have a whole extra month to collect your pennies. So, yeah, you'll need to hang on until December.
