I got the 512 GB model in Pacific Blue mainly because I could. For the 1st time in a long time money wasn’t a real object and for the phone I decided to go with the highest end model and biggest storage capacity. The stimulus payment and a bigger than expected tax refund gave me the money to upgrade my three main Apple Devices(I didn’t need the newest iPad or iMac for my useage) Spent a little over $3K back in April upgrading my devices. Also had to purchase a refurbished Windows PC for a possible work at home job. That was less than $300. I don’t use it but I have it if I need it for work at home purpose.I use roughly 50gbs last time I checked. I have the 12 Pro Max Graphite 256GB.
I could have easily made the 128 work, but I always like going for the in between storage. I always got the mid tier option, be it 128 or 256GB. At some point I look for 512 to be the mid option and I will go for that. It's just habit and I don't mind paying extra. Although I guess if 256GB becomes the entry level I might have to reconsider doing that.
