While many are oo-hing and aa-hing over the iPad, I have been totally besotted by my Kindle. When the iPad was launched, many people felt sorry for Amazon because they thought that the iPad spelt the death knell for the Kindle, which was launch just a few months prior.
Jeff Bezos (founder and CEO of Amazon) made a brilliant move; he did not give in or give up. He improved on an already great product (the Kindle 2), and dropped the price for the Kindle 3 (which yours truly immediately queued up to buy). Many companies were already making e-readers then, but few can achieve what Amazon did with the Kindle.
Back to the iPad. Many people are inclined to compare the Kindle with the iPad. Kindle is not iPad and iPad is not Kindle. The difference is not form or fit, but function. In my opinion iPad and Kindle can coexist. Use the Kindle if you want to enjoy the pleasure of reading. Use the iPad if you want to browse for information quickly; just make sure you keep your charger handy all the time.
