There's no rhyme or reason to my phone switches. Sometimes I switch because I just simply want to - other times because I wreck my previous phone.
I used to be a RIM Blackberry nut, and changed phones the day that new models came out.
With iPhones:
1. iPhone SE First Gen, kept it for about 18 months and wanted to upgrade to a larger screen
2. iPhone 8 Plus, bigger screen! Kept it for 4 years almost to the day. I decided to upgrade from this bad boy because the 13s looked real good
3. And it was! iPhone 13 for maybe 2 years or so, until Sept 2023 when I dropped it and both the front and back glass shattered
4. A Motorola RAZR 2023 folder! Pretty fun, very practical, but an undroid nevertheless. This one was knocked off a music stand, and I found myself suddenly owning . . .
5. My current iPhone 16e, which has been in my pocket since March 12 of this year.
I think my favorite of the lot was the 8 Plus.
