I have a carbon bike in fact it's my 1st road bike having just got bitten by the cycling bug. I wanted a light weight bike having had heavy lumps in the past. I also wanted a bike I was happy to ride and boy do like this one. Like others have said you will notice it on the hills. Your current one sound's the business bet it turns a few heads.
You clearly like and enjoy it. Sound's like it put's a smile on your face too. If getting a carbon bike will put even a bigger smile on your face and you have the funds go for it and enjoy. Sounds like you'd get use from having two bikes for sure.
