Why we need tablets in different sizes? One size does not fit all.

Almost two years ago, Apple launched the Ipad which has sold more than 55 million units. I have bought both the versions of the iPad and have been generally pleased. The one beef that I have with the iPad is that it is a cumbersome e-reader aka book. I find the original iPad and the iPad 2 heavy and awkward reading devices.

Compared to the Samsung Galaxy Tab, the Amazon Kindle Fire and the smaller version of the Motorola Xyboard, the iPad is 25% heavier. Moreover, the devices with seven inch screens feel more like a book than the iPad. I found my reading experience on these smaller devices a lot more desirable than the iPad. These 7″ tablets are similar to the form factor of most books.

Steve Jobs maintained that the screen size of the iPad was optimal and would provide customers the best experience. However, like it does in iPod’s,  I believe that Apple should offer the Ipad in a smaller versions – at least one smaller iPad. Here are the benefits to Apple:

• Access to a different and a potentially larger  market segment
• Lower cost product should increase sales further
• Complete product portfolio in the tablet category

If Apple prices an iPad mini in the range of $199-$249, I can see Apple sell at least sell 20 million units annually in addition to the iPad and increasing its revenue y $4-$5 billion annually.
