Everything is going to be amazing
I like this notion.
Well, I just read through this thread b/c I may have to consider the 32GB version due to budget constraints. What I've learned here is what I suspected: it all depends on your personal use case. And that makes sense.
I prefer the 128GB, but to think out loud for a moment...
- My N5 I gave up in August when I got my N7 was 32GB, and I always had plenty of space
- I LOVE using FLACS for audio, but even with that passion, I just occasionally put my FLACS on rotation monthly on my N5, worked fine
- My N7 was 64GB, plus I added a 128GB microSD. Sounds like nirvana, right? Well, for me, that meant I enthusiastically copied over about 50GB of FLACS - yippee, no more rotation! But in reality, my big storage N7 remained mostly empty, and I rotated my FLACS anyway - old habit.
- I've got a 128GB card in my car half-filled with mp3's. Sounds awesome, but I actually listen to the 5% or so that curate/rotate. If it was a tiny 16GB card I'd do just fine.
- Google offers free Cloud storage, which I use heavily for just about everything now, as I am a long-time Chromebook user/lover. This is a game-changer for me. My pictures are constantly scrubbed from my phone and automatically backed-up in Google Cloud in original format.
So, my use case is that I typically grab for the larger storage for my phones and for use in my car, but I actually rarely use it.
Again, it's up to everyone's personal use case - no one, hard, fast, way to go that will suit everyone. You just don't want to be disappointed in time, but it might be a good idea to take a close use at your actual (vs. imagined) personal use case.
