Imitation is the best form of flattery and many companies have launched similar versions of the iPad and I suppose, it also pushes Apple not to sit on their laurels and keep innovating and moving forward. Hence, the launch of the iPad 2.
My colleague has a box of one of our competitors. He says it reminds him on a daily basis that we have competition. :P I think that's clever! We might be number one and the leading brand but it doesn't mean that we can sit and assume we will be so forever. I love how the Swoosh constantly innovates and it's pretty inspiring. When the competitors come out with products that look similar to ours, it is actually flattering. We see it as a push to keep on innovating and progressing. Without good competition, I don't think companies could be as innovative as they are really.
Meanwhile, on an unrelated note, I should make a mental note not to listen to my Heytell messages from B.T in public. I played the one that he sent expecting a message like Where are you now? or so but out came his voice calling me in my pet name. Embarrassing! Silly boy!
