If you're happy with what you've got at the moment may as well keep going with it :) Though it sounds like now you have another of possibly too many options to consider should you ever decide to make a switch for whatever reason XD
The shots are pretty impressive!
Absolutely correct. You have to say to yourself how would this make my photo's better and photography more enjoyable. Btw I still have a 10 year old Canon DSLR camera that - IMO - still takes awesome photos!
