I Haven't had an issue and haven't been bored.

The fact that it doesn't work for you doesn't mean it doesn't work for anyone or that we are compromising. I for one don't find myself saying "I need this or that -I wish I could've had space for it in my carry on".

Edit: forgot to say, I also travel with a bulky gps watch in my bag (and its accessories) and my harmonica in my briefcase.
