During yesterday’s iPad presentation, Steve Jobs and company announced a handful of useful and elegant accessories for the yet-to-be-released device.  What they failed to announce, however, were the prices for these accessories.  But don’t worry, iLounge has obtained some of the retail prices for Apple’s iPad accessories, so now you can plan your future iPad purchases accordingly.

The iPad Keyboard Dock, which holds the iPad upright while charging it, and of course provides you with a physical keyboard, will cost $70.

The transforming iPad Case will set you back $40.

The iPad connection kit, which consists of a separate SD and USB 30 pin connector, will cost $30.

And finally, the VGA display connector, which allows you to send 1024×768 video to a projector or monitor, will cost $30.

As you could have guessed, Apple won’t be the only one providing accessories for the iPad.  Two other manufacturs have already stepped up and announced quite a few new accessories.

Griffin has announced five new accessories for the iPad, ranging from sleeve and silicon cases to screen care kits and protectors.

Elan Passport for Apple iPad: $49.99
Elan Sleeve for Apple iPad: $49.99
FlexGrip for Apple iPad: $29.99
Jumper for Apple iPad: $29.99
Screen Care Kit for Apple iPad: $24.99

All five accessories will be available in the Spring of this year.

Tom Bihn, maker of messenger and laptop bags, has announced two new bags that will perfectly fit the iPad. One is called the Cache, which is an iPad-sized sleeve, and the other is called the Ristretto, which is a vertical messenger bag with an interior padded compartment to protect your iPad. The Cache will set you back $30 and will ship within 10 business days of the iPad’s release, and the Ristretto will cost $110 and is apparently shipping soon.

These are just the first of many accessory manufacturers to jump on board, so don’t worry if you don’t see anything you like quite yet.
