I have three bikes, I have been riding for 1 year fairly seriously, too old to continue jogging due to boredom!!
A Moulton whch has 21 gears and has a 3 speed hub with a 7 speed derailleur (best and worst of both worlds). This was my first purchase and it looks unusual but is very capable for Sunday runs etc.
A Dahon 8 speed derailleur - which I take overseas when working away from home. Very good bike, I have even taken it on a Sunday run - BUT no one will ride alongside me. AND I can keep up on a 50 mile run.
A Raven Sports Tour - this is the newest and the best. I have started commuting and intend to do the 28 mile commute at least 3 times a week.
The Raven is brilliant to ride, gears are no problem, it allows you to change gear more often and apart from 7 to 8 to 7 you can change without thinking about it. ~Maintenance is minimal - so I resort to keeping it clean. I do 8 miles along the canal on my commute.
There is no way you can avoid not using derailleurs due to the cosat of the hubs - but I intend to ride the Moulton occasionally. The suspension on that bike is really comfortable and its one thing I miss.
I read all the reports in cycling magazines about how responsive such and such bike is - they seem to have ultra sensitive feedback mechanisms, I just get on my bikes and ride em. I trake pride in ownership because I have researched the various options in choosing my bikes and I am happy with the results.
I still am amazed how they have fitted all those gear trains in the Rohloff and its great to hear it whirring away due to my effort. Isuppose the people who have chosen Dura Ace etc think that they have also made the correct choice. Lets face it, like car makers the products on the market today are generally very good due to the global competition.
If you can afford one - buy it and enjoy it.
