The IS series is very comfortable to me. I have an IS-20 DLX and I also had a digital version, the C-2500L, which was interesting.
How many lenses do you feel are necessary? I have 3 lenses covering my whole range, though I would like to go a bit wider with a fish eye. Unless I sprout a couple more arms, I'm going to find it difficult to use much more.
It's not always "how many lenses" that is the critical issue, it's more what those lenses will do for the user. In some cases there may be overlap in range, for instance, but certain lenses are purchased and used for special purposes even though they may be within the same range as another lens. Macro lenses would be a good example of this. Another example would be if someone wants a basic "walkaround" lens such as the new Nikon 18-200 VR, which is a really great little lens, but not super fast. The user then may choose to purchase additional lenses which are within that 18-200 range but which are prime or zoom lenses and in many instances much faster. The value of a fast lens is in situations where there is low light.
Or someone might want a macro lens which again falls within that same range....
Taking myself for instance, I've got the aforementioned 18-200 VR lens. I love it -- this is really a superlative lens. However, when I want to do some shooting in the 100-200 range when the light's not so good, I've got two choices: one, kick up the ISO and two, choose a faster lens. I pull out my 70-200 f/2.8 lens and away I go..... Then there's macro. The other day I decided to play around with the new Lowel Ego lighting setup that I recently purchased. It's for tabletop photography. Just for the heck of it I shot one or two images with the 18-200 VR, as it happened to be on the camera at the time, but then I quickly switched off to the lens that I use for macro, the 105 mm. (I've posted my latest desktop, one of those images, in the Community > Pictures thread) If I have the urge to shoot photos of my kitty under natural lighting I am more than likely going to reach for the 50 mm f/1.4 lens. In a few weeks I'll be going to an outdoor event which will be held from late afternoon into the evening. I'll be starting out using the 18-200 VR but as it begins to get darker, I'll be switching to a faster lens.
The point here is that Nikon and Canon both have a lot of flexibility available in their lenses and this is what many photographers appreciate and need. I suspect that while Olympus has some good lenses that perhaps they just don't have quite the wide range and breadth of lens choices that are available through the other two manufacturers.
