In one respect I'd say Apple is not in decline, but in another respect, I feel Apple lost its soul if you will. What I mean by that is, making great products, and innovation seemed to be what was important. Steve Jobs and his folks who literally go over pixel placement. They were zealous about designing the right product, sure they messed up and laid some eggs, including the G4 cube and the infamous mold lines, or the Titanium Powerbook and its finish flaking off, but overall design, function and innovation seemed to be of primary importance.
Now we get products like this.

The focus now is on profits and money, they seem to be more concerned about stock prices and where apple fits in, i.e., most profitable company, first to hit a trillion dollars etc. The move to stop reporting units sold is a thinly veiled attempt to hid the fact that sales are decreasing. The price hike in all of their products, were offsetting that to some degree but that's just a short term fix. As people are less willing to spend that much money and so we're seeing the longer term consequences of the price hikes.
Overall, I think apple produces great products, but they've made some questionable strategic decisions on their products that may impact my ability to buy them in the future. If they value profits over innovation or making insanely great products, then they will continue sliding.
