Its the same if you plan to buy a new iPad or iPhone or smth. like that. Mhmm...do I buy? Or do I wait...
You can wait forever if you want, because it will always come a better, newer or bigger version of a product.
In my opinion: don't wait, just do it! (Shia LaBouf Voice)
I cordially disagree. I do not think it is about waiting for a long time. It is more about the developer's commitment to releases. For example with Affinity Designer and Photo, their releases are very few and far between. So we have no choice but to take the leap of faith. But with Overcast (the podcast app), I know a x.1 release is going to be released shortly after a major release). In fact in their last major release of 5.1, we got updated to 5.1.1 quickly - within a month if I remember right. Same deal with Lumafusion... about a month between .1 updates.
I have ALWAYS regretted getting the brand new version. Same with getting new cars (and computer hardware).
Mostly, I have benefitted greatly from waiting just a bit on x.1.
Based on knobbydave's reply, I will wait 'til 2.1.
