I suggest restarting your Pro and closing all apps not in immediate use to maximize your free RAM. I'm still rocking a Mini 2 (1GB ram) and it is NOT "constantly refreshing web pages" and apps are not "losing their place" UNLESS I have a number of tabs open and/or too many apps open. Empty your 3X-more-RAM than I have and I bet your experience will improve.
I have friends that were griping about "slow" iPads. In helping them, I always look at how many apps are open- usually every app they've ever opened because they don't know how to close apps- and then I show them how to restart their iPad to flush out any memory tied up for nothing. Magically, after freeing their available RAM, their iPads speed up.
I'm finally jumping on this 6 myself only because the 2 is no longer getting iOS upgrades and some apps I use seem to really "want" new iOS functionality. Since 1GB RAM still works pretty well on the 2, I'm thinking 4 times that is going to be amazing instead of "low."
Of course, we can always want more "specs" stuff. Had Apple put 6GB RAM in, someone would gripe why not 8? If there was 8, why not 16? There are plenty of posts about the A15 being slowed just a bit from the A15 in iPhone. Why not M1? Why not M1X? Why not M1X AND Intel so we can run Windows too? Why not a card slot for dedicated graphics? Why not 2 card slots?
I can "want" with the seemingly many craving what would be the iPad Mini Pro (though many posts read like they don't want to pay up for such a pro at what would likely be $1000+). Had Apple also rolled out such a pro, I would have paid the difference. To me, that would be the perfect Mini.
But this is what they offer. If we like it, we buy it. If we don't, we can buy something else or buy nothing. How dollars actually flow is the only tangible way to show Apple if they made good or bad product dev decisions. Coming from the "2" and this form factor being "ideal" IMO, it was a no-brainer purchase for me. For others wanting features not available here and/or wanting what is available here for substantially lower prices, this is not the product for such people.
I excitedly await this loaded 6 to arrive. Yes, I certainly wish it cost less, but I could have that same wish if it was priced at $600, $500, $400, $300, $200 or even $100. Much like the Mini 2's useful longevity, I expect this one to still be in daily use 4-6 years from now. Spread even the max config specs over- say- 5- years and we're talking < $200/yr for a daily use tool/device. Meanwhile, over in iPhone threads, people are clamoring to spend $1599 on (maxed) iPhone MAX that they'll be spinning as "long in tooth" as soon as next year or the year thereafter to rationalize paying $1799-$1999 or whatever Apple wants for iPhone 14 or 15. Many woke up in the wee hours desperately trying to spend much more than this cost ASAP... and then are gushing if they were "lucky" enough to get one.
