I am in the camp that there is a benefit to the managed store. Since moving family members to iOS devices the number of times they have loaded malware or asked me for help installing ANYTHING dropped to zero.
Should techies be able to side load if they want? Sure, should that be a primary install method? No.
Current generation wifi 6E and 7 add 6Ghz which offers substantially more bandwidth / speed.
Wifi 7 also allows devices to use 2.4/5/6Ghz at the same time instead of just hard switching between them.
Would be a major setback since 6Ghz allows devices to easily hit Gigabit speeds wirelessly.
