Just waiting on WWDC, equally am looking at Windows systems, as I strongly suspect all WWDC will deliver is a bunch of old guys exaggeratingly proclaiming the awesomeness, of what is basically just another mediocre product, that in real world use is hardly of any improvement on previous incarnations.
If I had to sum up Apple in one word it would be underwhelming, therefore no surprise sales are dropping...
Q-6
Riding the crest of the wave of the most successful company of recent times is not always rewarded as a user when the basis of success is highly dependent on popularity in a niche sandbox.
Apple products have never been cheap for many reasons but non more so than it's consumer base
Apple exploited a desperate market in the US due to it's more unique set-up of restrictive practices of it's telco providers
Apples clever marketing in the US was echoed around the world via the internet due to a US dominance of presence in the English speaking community
Apples success steamrolled other products over it's competition
Apple ECO is a double edged sword
Apples US based model is not as easily transcribed across the world
Apple fashion status is victim of it's own successes
Apple core foundation is neglected as diversity increases and shifts
Apple innovation is hard to continuously repeat
What ever had drawn you to OSX/MACS, 5/10/15 years past, be it the underdog with unique and boutique appeal or a fresh style/appeal to consumer comms and laptops of recent times cannot keep pace with the ability of others to catch up and surpass in a market where the latest has a lifespan of <12 months
This is all PHD in stating the obvious

and many are happy, all be it possibly with indifference or ignorance
I think what is different about Apple is the polices between devices and services that includes upgrades and new releases are cleverly constructed to increase yields with less perceive value to it's consumer or have catches and induced restraints to propagate purchases and worst still to those that feel they supported Apple over the years and had a connection now feel detached to the new Apple monster driven by other factors than it's once more true values led by one man.
