The iPad comes with it's ups and downs. For some habitancy it might be a better choice than a netbook although they still have their advantages over the iPad as well. What are some things the iPad might be better for?
The iPad is much lighter than any other netbook on the market. It's designed is made in such a way that it's easy to carry around your house, put in a book bag, or hand to someone else someone quickly and easily.
It comes on much faster than a netbook. If you need to quickly check something with only a few minutes of time, you can have completed your task on the iPad before most netbooks are booted and ready to go.
The iPad has the benefit that the screen can be horizontal or vertical. Even with the same sized screen, one can use their iPad to get the best viewing angle for that specific web page or application.
By default the iPad has an all day battery that is good for 10 hours. Many netbooks out of the box only have about 3 or 4 hours of battery life although this can be upgraded.
One can get a 3g connection data plan with the iPad meaning this expedient could be beneficial in most places where you travel with it. Some netbooks do have this feature but most of them do not.
Some netbook users will disagree because they use their netbook differently and make some good arguments because the iPad is lacking in many areas. But there are some principal advantages for those who want a simple, easy internet and media device.
