'iPad will not replace your notebook or phone'

After weeks of buildup, the iPad finally debuted Saturday in the US. The sleek device went on sale at Apple stores around the US and at branches of the leading electronics chain Best Buy, as well as through Apple's website.

Long queues of consumers eager to be among the first to get their hands on the iPad waited for stores to open across the US, reports CBS News.

'Early Show' contributor and CNET senior editor Natali Del Conte, has come up with some of the pros and cons of the device.

Some of the drawbacks of the iPad:

• It doesn't multi-task
• It is a fingerprint magnet. For something so elegant, it sure does look pretty grimy after a few minutes of use
• It is heavier than you think it is. Using it as an e-book reader can be difficult if you are planning to hold it like a book for prolonged periods of time
• Typing on the keyboard can be hard to get used to. You have to set it down to place your hands on the keyboard, which is awkward and odd. I don't think you'll be composing long e-mails on it
• It will not replace your notebook or phone. You won't be able to produce a lot on this. It is meant for you to consume media like music and video. Producing things like video, photo, or written text is not really the best experience
• It is expensive for something you're not sure you need yet. There is always the chance that Apple will lower the price in a few months like they did with the iPhone. There is also a very good chance that a camera will be installed in the next installation of the device so if video calling is important to you, you might want to wait
• It is not a high definition experience. High resolution but not HD
• You cannot annotate your books from the iTunes store so if you are reading a book you bought through Apple, you can't take notes on the book or mark passages like you can on the Kindle
