RMB: Given that you're looking for casual rides, I think that what you've got is outstanding and the fact that you find it comfortable is very important.
But, if you're planning on 1-2 hour rides, you might "catch the bug" and want more than that model offers. So, if you have an inkling that riding may evolve for you, then zen is spot on in her feedback (she knows her stuff).
If it's an option for you to own two bikes, then go with what you have...and get another one later.
If you don't grow where you're planted, you'll never BLOOM - Will Rogers
