For actual authoritative word definitions, usages, and spelling variants, I use Oxford English Dictionary - it requires an account but most libraries include free access.
For quickly finding synonyms (and similar utility stuff) while writing, my go-to for the last few years has been WordHippo. There are plenty of other sites that give synonym lists, but in my experience WordHippo surfaces way more variety, including idiomatic expressions and slang.
I think it depends on the types of photos you tend to take. If you’re mainly taking portraits and candid ‘capture the moment’ type stuff then I don’t think the Wide format has much to offer besides physically larger photos - if anything it’s bulkier to carry around and more awkward for shooting.
However, if you want to capture landscapes and other scenes that actually benefit from having a wider framing, then it might be worth it. (But also bear in mind the Wide film is more expensive per shot and harder to find in stores.)
Edit: just realised the Evo cameras specifically are ‘hybrid’ cameras, not pure analog instant like the main Instax line. Not sure how that affects image quality, but I’d imagine it might have a shorter lifespan due to the built-in battery (and possibly hard to replace) and more complicated inner workings. More things to go wrong over time. If you’re looking for a reason not to buy, that might be it.
