I expect more and more to be locked down. Not so much because of desire by companies to lock their product (although that is a motivator), but media sensationalism and politicians need to look like leaders while expending no effort. I look at the case of the startup uploading all the addresses found in the contacts of an iPhone and the reaction to that. I did not see one article asking if someone's Outlook for Windows contacts had ever been uploaded. It was a stupid move for the startup, but given the history of PCs, it seems like something post-PC product managers would overlook. People seem to want to share everything, but have control over privacy. Adding to that, I am sure a push to make absolutely sure security measures (remote wipe, find my phone) cannot be disabled by a thief. All this gets us secure, locked devices, because it is easier than having your C-level executive be lectured to by some member of Congress's committee.

So, I would expect to see less and less of people in the industry who got into like me with and Atari 400. There are certainly no modern day version of the C64, Sinclair Z80, or TI-99/4a (no, Raspberry Pi isn't even close).

iOS provides great software to start every career but the one that makes it sing.
