Sure I could. For example: the IPod is now facing serious competition. No doubt I could find more if I followed the stock, and especially if I read the financials.

Not likely. Apple is about to grab another 5% of the market easily over the next coule years. 5% might not sound like much, but it would be a 50% improvement over what they have now. Expect a forward split in the next few months.
