As for the future of Apple.
I think Apple was/is considering worse case scenario when they released the iPod. They got into the online music game because they knew it would drive iPod sales. Some reps from Apple have commented that iTunes is a means to an end right now with iTMS sales barely breaking even. And that end is to drive iPod sales. There is a distinct possibility that in the next few years iPod sales will outpace Mac sales. Apple is looking at the small consumer product market with a keen eye right now to potentially drive their bottom line in the future. IMHO they havent release anything else mainly because of the growing competition against the iPod. I think after the market settles one way or another, prob within the next 18-24 months, we are going to see more consumer devices being release from Apple. The thing I cant figure out is where they would go.

-Cheap, relatively speaking, home theatre systems that link back to your Mac and PC?
-DVR systems that link back via WLAN and internet back to your *book to download the current episode of your favorite TV show or news program?
-Portable e-book reader that uses

-My personal favorite. A combo landline phone and VoIP phone that attaches to your Mac or PC and works across iChat AV and AIM. So the base station connects via Firewire or USB2 to your Mac or PC and your phone line connects to your internal modem to allow you to record VoIP chats and landline chats as well with caller ID to the hand unit that distinguishes VoIP/landline with a globe with a lightening bolt going through it or a telephone poll. Yah so thats all me. But I want one dang it!!
I dont think Apple as a company is going anywhere but I do have some concerns about Apple as a computer company. I think some interesting things are going to happen in the next 5 years with Apples computer segment. I consider it sink or swim time for Apple when it comes to their computers. Contrary to the naysayer they are still here. But they arent anywhere near where they were 10 years ago. Instead of a quick death its been a slow bleeding death with a few pints of blood being administered here and there to keep the patient alive.
Apple still has a number of things going for it like their beautiful designs and their OS but I will counter anyones claim of quality. I have one friend who has had his system board on his iBook replaced 3 times over the last 2 years. Right now as I type this its going in for the fourth replacement. Ive had another friend who has had 2 system boards go south on him. And several friends who have had 2nd and 3rd gen iPods die on them.
We wont get into some of the software updates Apple has released that have done very bad things to peoples OSs. (Yes Im aware of Win XP SP2s growing reputation at being craptastic.) So I consider quality to be a diminishing feature of a Mac.
That leaves the OS. But frankly as good as OS X is, its not as if I can go with another hardware vendor who has a better rep. The OS and the hardware and tied together. If one sucks the other will as well. So where does that leave them? Certainly not dead but sure as heck in no position to ever take on MS and its fleet of OEMs head to head ever again. Apple's wares needs to be better, stronger, faster then their competitors and IMHO when it comes to their computers this just isnt the case anymore. I hope for a major turn around beginning with the G5 iMac but Im not going to hold my breath.

Something will happen to marr the G5 iMac. Possibly issues meeting demand? Possibly quality concerns? Who knows but it seems as if something HAS to go wrong with a launch of a new Apple product. I'll still keep my fingers crossed and hope for the best though.
