Now it’s a week or so later - and virtually all of my computing has moved over to the iPad. Again, as I stated in the OP, my computing needs are not as intense as many people’s - therefore I’m hesitant to “proclaim” that the M1 iPad Air is a true replacement for a PC for everything. However, for moderate spreadsheet creation/use, word processing, recordkeeping, social media, internet research and website maintenance, and moderate gaming (i.e. Roblox & Minecraft) the iPad Air Gen 5 is quite capable and has replaced my PC.
EDIT: I will add that when switching computing tasks to the iPad Air, Google is Apple’s best friend.
