$1300 to open doors to more shooting opportunities/possibilities vs what I've invested for my Canon kit that doesn't? Also, I consider the fact that I have a closet full of lenses each of which cost around the price of the x100s or more? In a nutshell, just do it!
I think this is a point not many take into consideration. Most of my Canon lenses are more costly than the X100S... in the end, it's such a minor investment that it was hard not to buy.
The rumored FF fixed is not what I want or need, pretty much have that covered at this point... I may not even need a Fuji FF ILC, it's more of a want than a need. The thing about this X100S is that it opened doors for me that nothing else I own did. It met a need and a want all at the same time.
With the GAS situ (I suffered for years), I collected cameras... Canon, Rollies, Leica, Nikon. Much of which stays tucked away in Pelicans or in cases. You only have two hands and can carry so much... I began to realize what was important was finding gear that helped not hindered. My Canon's help with work, the X100S helps with the family and everything else I enjoy about photography. It brought me back to the days when I only had my dad's old 35mm, beat to hell and I didn't care. It was easy and fun, I enjoyed taking pictures for the sake of taking pictures. It wasn't about bodies and lenses at that time, somewhere I got a bit lost and afflicted with GAS. I'm recovering now, baby steps... at first it was hard to not carry the backpack, the 5D3 and yea a second 5D3, oh...and the 50, and the 135, oh...yea the 70-200 might need that and while I'm at it better take the 24-70... it was a vicious cycle. It is totally liberating, I reach for the little Fuji and then grab the diaper bag... that's it!
So you goona start that thread John or should I? Dylan and John, you guys on Flickr? Local to Cali? I use Flickr for social stuff, camera clubs and meet ups... you guys every done any of that? Check page 4 of this thread... I have my profile info there if you're interested.
I actually tried to send you a PM from my phone but just checked my sent messages and realized it didn't send. Wasn't trying to ignore that post. lol.
Anyhow, I do have a Flickr account but nothing on it really. My buddy has been trying to get me to register at 500px. Will link up with you on Flickr once I start using it regularly. Most of my stuff is for family and friends at this point so FB (as lame as it is) and emails are where most of my stuff goes. No clubs. My buddy keeps trying to get me to come out to meet with the locals from FB (here in Cali) for their monthly meets but haven't gotten felt inclined enough to use one of my hall passes for it yet.
I'll leave the other post to you. Wasn't sure of exact title or where it would be best served to post to (categorically).
Re the Fuji, it really does take me back to basics and relieves me of all my concern about what I need to pack. I seriously have just the cam and a battery in my pocket now. I had been going through the same thing you mentioned as far as packing goes. Oh I'll need this, but wait, what if I need that....
Some more specifics on the mental work I did when making the decision to buy the Fuji. Before pulling the trigger, I had a 50mm lens in each of my hands and one sitting in front of me totalling roughly 4k in cost all together. I was trying to decide which one I wanted to take out that day or if I should just bring two. At this point, the light bulb goes off and the epiphany sets in. For about the cost of any one of those three 50mm (or the 24, 35, 85, etc etc), I cured myself of this thought process and freed myself.
