I find it fascinating that HP continues Pavilion and Dell continues Inspiron. I imagine it's still profitable to offer entry level Wintel PCs, of course, but Chromebooks have been out a long time now, and so they are developing and producing multiple affordable lines of PCs, more than they have to, while also supporting more and more brands above it: Envy, Spectre, Victus, Z, Omen, EliteBook, ProBook. Surely there are diminishing returns when your own brand isn't as well known as Apple?
I'll add that Microsoft themselves don't bother with this segment, probably due to profitability.
Of course hardware needs a name, but why keep Pavilion, particularly when so many people will have had bad experiences with that name? A no-name number might be more effective. Apple is phenomenally profitable with, what? 4 laptop models? For businesses and for retail customers, of course keep the hardware diversity, but the names and the lineup overlap is clearly unnecessary.
