I feel I have to try and clear up somethings, I think there may be some miss 
understandings here about what a input and what a track is.

-
In a digital world there is a big difference between the number of external 
inputs/outputs you have and the number of internal tracks you utilize.

Many external inputs are mainly needed if you _need_ to record many sources at 
the same time, ANALOG sources.
Like if you are recording a symphony orchestra you may wish to use lots of 
inputs to capture a room fully. 
If you record a 4-piece rock band - live - and wish to have great control of 
the result, you probably need between 8-16 inputs. If you don't record live, 
but rather take it one step at the time you need nowhere near that amount of 
inputs.

Another reason for having lots of inputs (and outputs) is that you may have 
external effects that you wish to route the signal through. This is quickly 
going out of fashion, atleast in my world, hobby musican. I work entirely 
inside the computer once I got the analog sources recorded.

--

Internal tracks on the other hand exist only inside the computer, normally you 
mix these inside the computer before sending it to a output (e.g. monitors). 

These can normally be created and utilized almost unlimitedly. It is true you 
can't record an unlimited amount of channels, but the limits are normally not 
a problem.
Of the top of my head I'd say that 100 playback tracks should NOT be a 
problem. (_Should_ not be a problem, I imagine few people are trying the 
limits right now in Linux audio, programs are probably not fully optimized 
yet)
Working in a computer you are not bound to a physical number of tracks that 
you must "fit" your music in. Rather you would probably start creating tracks 
as needed, group them as needed. 
Later in the composition if you for instance needed to add a distorted Oboe to 
get those wierd tones that define your speed metal recording, you would not 
reuse a track that wasn't utilized at that point. Rather you would create a 
NEW track to keep the composition well structured.
(reusing tracks is probably not applicable to pro recordings, I imagine they 
would NEVER reuse tracks, when there are no more left, there are no more 
left. In a home-recording situation, e.g. 4-track or 8-track it is quite 
common to reuse tracks though.)

Conclusion: in a fully digital recording studio there are no real limits to 
the number of tracks you can utilize. You tend to use MORE tracks than in an 
similar analog situation. Just because you are allowed to structure things 
much better. This provides a much better basis for realizing your 
compositions, you have less constraints to take into account.

The number of external inputs and outputs you need is defined by the number of 
concurrent audio sources you wish to record/listen to. If you record step by 
step and use artificial drums, like me, you don't need more than say 4 inputs 
and 2 outputs. The more advanced you get you probably need more inputs and 
outputs, but very few people need 24 inputs in a digital studio.
