If you are an "Old School Mac Guy" as your forum name says then you know your first sentence is nonsense because the current 27" iMac has a RAM door for user upgrades. Tim Cook mentioned them when he introduced the model even. But the current iMac likely had a lot of input from Jobs during the design state. He appreciated the fact pros liked to upgrade and accomodated where possible. The previous generation Mac Mini was also quite upgradable and the access lid was screwless. Again that was launched under Cook, but a Jobs era design.
But, yes, you make my point... this TC version of Apple is a pale image of the Jobs II Apple in terms of the detail it goes to to make products "insanely great" for anyone who buys it, marginalizing no potential customer if possible. The MBP is not a pro machine, it's a consumer machine with a slick marketing name. Of course, in reality is a MacBook Plus, so you are correct, the soldered SSD won't hinder sales unless Apple missed the market and consumers are put off by the price too. We'll have to wait until 1Q sales to see how that turns out.
There doesn't seem to be any exigent reason why the SSD was soldered in except to prevent people from upgrading if they wanted to or save a buck. As an old school Mac guy myself I find it odd that you would so veheminetly defend the indefensible here and welcome our new weak sauce laptop maker overlord. Apple should be careful before burning its bridges because if us old loyalists get turned off and tired of the brand then the more fickle public isn't far behind.
The Mac Mini update made Timmy's intentions quite clear. Despite no change in form factor, they purposely made the machine difficult to impossible to upgrade. Apologists couldn't even use the "Soldered because they made it smaller" excuse.
The next major iMac body revision will definitely see the end of upgradeable RAM on the 27" iMac. I'm sure if Apple could solder 5400rpm HDDs to the iMac's logic board, they would.
