papatomack,
I started with an inflatable and thought it was the cat's butt until I paddled my first rigid boat. I still have the inflatable, but it hasn't been wet in years.
With few exceptions, the difference between inflatables and rigid boats is night and day. If storage and transportation is your biggest issue, then maybe you're stuck, but if you're really interested in the real kayak experience, you've got to try out a sea kayak and preferably a composite boat. Yes there is a tremendous difference--the difference between a balloon and an F-16.
However, be advised that not all sea kayaks are equal either. Take the time to learn something about the different types etc. and if possible, try out several different models and brands.
