'If you're thinking of getting something to replace your old PC, think about getting an iPad, which we believe is where "personal computing is going" '
Seemed a fair enough marketing message - to show that you don't have to have a PC to do (personal) computing. Apple does use "PC" to mean Windows PC, but don't explicitly say - they're seeing Macs as separate to what they'd call PCs.
Apple I guess knows the number of people new to iPads, Apple who are coming from PCs. Why not market to them?
And whilst the ad in the keynote didn't show it, this could also expand into a play to court enterprise/business who are also likely to have ageing PCs.
I'd echo
justin216 - having set up a family member with an iPad Pro, another looking to get a 9.7 iPad Pro (having never had their own PC). The majority of Apple customers aren't necessarily going to be tech savvy, or have the skills to use a Mac or PC that well - and the simpler iPad can be a boon for them. Apple is making products, and marketing to these people.
We just have a wait on our hands for Mac updates. But hey, as there weren't announcements at the event, there's still the possibility that the supply chain is leaky enough that we see some rumours, parts etc prior to any Mac refresh. Though waiting a few months up to the end of July seems more likely now.
If Apple is waiting on new parts, say Polaris from AMD, AMD not knowing when they can ship Polaris presumably affects Apple's ability to announce and release Macs. Same with Intel & AMD for say Mac Pro.
