Why would it be delayed. Apple is no longer a compter company, but a small tinket company with its iPod & upcoming iPhone. You noticed that resourses wre not taken from the iPhone to bring out Mac OS 10.5 on time. But rather the reverse was true. Resourses wre taken from the Mac OS development to be used on a limited market gadget.
The iPhone may look cute & fill a small niche market, but is being late on the release of OS 10.5 late & looking like MS really worth the price. Because Apple is now a trinket company they seem not to be concerned with the loss of sales, loss of image & loss of keekping the Mac Computer User satisfied.
I know only one person that has AT&T cell phone service & he doesnot have the money to purchase an iPhone. Those, like me, that have other service have no plans to purchase such a seemingly high priced cell phone gadget or trinket. My son had his cell phone & PDA tied together, but had to replace it because the cell phone no longer operated. When he purchased new he went with a Palm for his PDA needs & a separate cell phone for his phone needs. He said that he would never again get a combined device. Apple research seems to indicate that my son is in the minority group. I for one never went the route of a combined unit. I have a Palm PDA, an iPod for music & a Motorola cell phone for my phone needs. Why would I want to combine them? Cell phones needs to be replaced too often in my opinion to have large scale devices in the same package.
