@Claude31 I've mentioned what I'm gonna do. Browser with ~15 tabs, Intellij(for coding), discord, MS to-do app. I'll use FL studio & some graphic designing tools(beginner in designing). Also, I don't use Xcode, current Intellij Java project on windows is 2MB in size. I don't know how discord & other apps fare in mac.

No, I don't notice like tiniest of lags. On storage front, planning to get an external SSD.

@Claude31 Tbh, not really sure. Currently into software development & mostly will stick around or might switch to something else like music or graphic design.
