About 3 years ago Apple Computers began an advertising campaign and section of their web site; "Switch" dedicated to the Windows users who recently switched to the Macintosh platform, or as Apple puts it "seen the light". The just of the campaign was just to share the stories and experience of prior Windows users who recently switched to the Macintosh platform. With PDAs there had been a similar migration, but from Palm OS to Windows Pocket PC, but the stories and experience is not as favorable for Microsoft.
I recently was speaking to one such PDA user who switched from a Palm device to a HP iPaq. One important thing is that this individual had been a happy Palm user for many years and the only reason she is using an iPaq is because her previous Palm died on her, and her (non-technical) boyfriend decided to buy her a replacement, but bought her in stead a HP iPaq.
For a layman average PDA user, the iPaq and more specifically the Windows Pocket PC is not as easy to use and more complex compared to the Palm OS. After a few months use of the iPaq she is now fallen back to use Post-It Notes. It got to a point where she has Post-It Notes stuck to the back of the iPaq. Now that is ironic. Unfortunately, I did not have a camera with me otherwise I would have a picture of it here.
This individual has decided that she will purchase a new Palm device very soon.
So as you can see forcing people to switch is not the right approach. Apple and Steve Jobs had the right idea. Steve always thought that his company has good products and they will just speak for itself. So he and his company just concentrate on developing amazing revolutionary products.
