The iPad is a good device. It would not have sold, what, 4 million units or something so quickly if it wasn't. Sure Apple's brand name helped but the product delivers.
If a product sells that quickly, there is no way anyone can claim it is a good product. All the people who pre-ordered it / bought it first week / first month, make up a majority of the total sales. That means, the product is untested, and people are purchasing only because of the brand name, and on the basis of their previous products, and the company's claims of how the new product will deliver.
No doubt, the iPad is an exceptionally built product, but how much of that built actually transforms into utility is a question, of which I am still trying to search for answers.
Yes, it is a useful gadget to have when you're relaxing on the couch and couldn't be bothered to hold a laptop/netbook because of its form factor, and you quickly sift through the web-pages, but I'm sure 4 million people didn't buy it for that reason.
If the iPad was capable of being a standalone device, I would have voted it the device of the century, for possibly starting another revolution, but to the contrary, being standalone is a far off statement! It needs "iTunes" to put anything on it.
I hope it is copied by some good manufacturer, and put to good use.
I respect Apple for being innovative, but it lacks enterprise. Remember, the computer was made what it is today by Apple; It also invented the mouse.
Had it been a more enterprising organization, I can't see why it couldn't ever control a worthy market share. Look at Microsoft, look at IBM. Both are pioneers in their respective fields, and are still very much the market leaders. (Can't say that's completely true about IBM, especially after it sold the PC division to Lenovo, but, to be fair, PC was never its area, but nevertheless, compared to Apple, it is still far ahead.)
PS: I'd like to add an exception of the iPods, which have completely dominated the mp3 player market. Also, iPhone to certain extent, because they have a large market share, and a potential for a lot lot more, but I don't think that potential will ever be completely fulfilled.
That ends my rant about Apple. I hope it is taken in a positive sense rather than negatively.
@Rohit, sorry for quoting you, but that provided a good starting point to lend my views on it.
