Apple are now, essentially, developing for three different operating systems: the iPhone OS, the iPhone OS (iPad variant), and the Mac OS. And they're forcing third-parties to develop for three operating systems, too. (It might be relatively painless to convert iPhone apps to run on the iPad full-res, but to do that well will still take substantial effort). Personally, I'm a little worried the iPad will spread the company's focus thin: will Apple release an update to iWork this year, or has the iWork team been so pushed to develop the iPad version that the Mac version has been overlooked? I remember when Jobs entered the stage in '97, he promised a return to a simple, un-convoluted product line. Now, I have the feeling the company is releasing new products simply because they feel as though they need to continually expand the product line. Thoughts?
