People worry about Microsoft keeping tabs on them but I worry far more about Google. There have been some serious security incidents involving Google and they try to keep too much personal information on people. And now we have these people saying that cloud computing will replace desktop computing? I am supposed to trust Google? I don't think so. There is enough security issues today without having to trust somebody online somewhere for the security of your information, documents, etc.
Netbooks and iPhones and stuff like that are not the answers for everybody. I do a lot more with my computer than just sent email, visit websites, and type up simple letters. I need a computer that is compatible with scanners and printers because I do photography. Businesses need more than just a simple word processor because of all of the needs of business. So it is important to have software like Microsoft Office. And Microsoft Word and Office are so widely used a person needs to be able to use that software. Like I said above, even a lot of Apple users use Microsoft Word or Microsoft Office (Microsoft Office for the Macintosh).
There are a lot of reasons I left Apple. Some of the reasons I will keep to myself. I can remember when Apple desktops were fairly reasonable in price-somewhat more expensive than Windows computers but not to bad. Today a real desktop computer like the Mac Pro is insanely expensive. I am willing to bet that if Apple allowed people to build computers that used the Apple operating system many people could build quite acceptable computers running Mac OX X for a third or half the price that Apple charges. People, Apple Computers are computers. I don't like all-in-ones (iMac) that much because if the monitor fails you lose the entire computer (or face an insanely expensive repair bill from Apple unless you have expensive extended service).
Apple now makes a lot of its money from iPhones, iPods, and stuff like that. In fact only about a third perhaps of Apple's profits come from computers. So Apple is kind of a consumer electronics company today.
I can't stand the cult-like insanity of some people who use Apple Computers and some people involved in Linux. There is a lot that could be said about that but I will just say this-everything from Microsoft, Apple, Sun, etc., is just technology. The technology we use today will be replaced by more advanced technology (unless the human race becomes extinct). I don't think technology should be something that people worship. Whatever computer technology you are using today will someday be replaced by more advanced technology in the future.
