iBooks + Retina Display = death of Kindle (the device)

Two features of the new iPhone 4 which did not get the love they deserved, as they were overshadowed by Face Time video calls and bright, shiny things, are iBooks and Retina Display.

iBooks is the iPhone's resident app for browsing and buying ebooks. Now, with the iPhone 4, it offers synching between your various 'iOS' devices (say, your iPhone and your iPad and your children's iPod Touch). This is a great feature that Kindle offers (enabling you to read your ebook on your iPhone or Android, for example, when out and about, and then accessing it -- from the spot you left off -- on your Kindle reader when you're home.

Kindle no longer has this advantage, thanks to iBooks.

Similarly, with the new Retina Display functioanlity on the new iPhone, text and images are radically improved.

Oh, and unlike the Kindle device, you'll always have your iPhone with you -- to call, to video chat, to play games, to browse the web. With the iPhone 4 (and especially for those families that have an iPad as well), there is simply no reason to buy a Kindle.
