Let's talk the advantages and diadvantages about iPad

So far I have not felt a 'need' to own a iPad as it will be just be 'more stuff' I have to upgrade and maintain. How has it benefited YOU over what a laptop already provides? Let's talk  the advantages and diadvantages about iPad.

Advantages:
1、more portable
2、more fast as it has sorta mobile version of the Internet
3、more screen realestate that an iPhone or iPod touch
4、cool apps just for ipad.
And the list goes on but I want to try and keep this relitively short.Time is real factor for the success of iPad or you may say iPad is the first tablet or Netbook like device which is successful.Many professionals are using iPad for their work. News,that a lawyer took out iPad for some reference, was floting around last month. 1 in every 4 doctors are either using or will be buying shortly.

Disadvantages:
1、no flash
2、no USB
3、no upgrade memory
4、a bit more money
Apple’s mobile devices do come up seriously lacking is connectivity. Just like on previous iPads, the iPad 3 only has a single output, Apple’s proprietary 30-pin data and charging port. There’s no HDMI video output, no microSD card slot for expanding memory or reading a card with photos from your camera, and USB port for connecting peripherals or memory sticks. Admittedly most of these things can be achieved using adapters, but these are expensive separate purchases, and they’re extras you need to carry around and remember to bring.

It maybe many other disadvantages about iPad,we can continue to find them!
