Yes, I feel Apple lost it's edge when Steve died.
Many things haven't come from Apple since than, and many things that have come would not have cut it with Steve I think.
They are no longer setting trends, but following their competition, which is a bad place to be in a market.
I also feel like they have abandoned the "Pro" market, without fully admitting it.
I was in the market for a nice Apple desktop this year. I ended up buying a 2012 Mac Pro second hand cheaply, adding SSDs, 32 GB RAM and a NVidia GTX980 (with MacVids rom from their UK reseller).
No iMac, Mini, Macbook (Pro) can match that thing, and I get really close to 2013 Mac Pro performance for a fraction of the price. Waranty could be an issue, but probably the thing will work for years.
When I bought my first Macbook Pro, just after they switched to Intel. I made a comparison, and a Dell with the same specs was more expensive. They were selling really competitive hardware for competitive prices. And most of it latest generation high end tech that worked well as a "Pro" desktop replacement.
After 2010-2012 I haven't seen anything from them that I really thought was competitive and that I would want to buy. That's why I'm running a 2012 Mac Pro and a 2011 Macbook Pro. There is no compelling reason to buy anything newer from Apple unless you really want a retina display. Before 2010 this was different.
