Well, I realize you wrote off iPads, but keep in mind that there's a whole community of app writers that are thinking music use of these devices.

The worship leader at our church uses OnSong http://www.onsongapp.com/manage/

I have used his iPad with it. It's great. If I had an iPad, (for which I am slowly saving) this would be in the top 2 or 3 apps that I would buy for it straight out of the gate, no questions asked.

You enter the tempo at which the song is supposed to be played and it slowly scrolls the chord chart to match the chart/tempo combination.

You can make set lists, etc. It has a flashing metronome if you want to use it, foot pedal controls, etc.

So, while the iPad/iPhone in some respects has limited functionality, in terms of music applications it actually rocks pretty hard. For example, how many music apps are there for Android? Almost none for two reasons; there isn't a standard API for music use (like core audio on iOS - which is a very low level functioning code set from my understanding) which means that someone like the original MIDI team need to step up and write out the standard.

I would write to the OnSong folks and ask if there is a recommended app for PCs that does similar function as OnSong.

It is text based only for quite a bit of the functionality - like how to arrange the played song order for scrolling (called 'flow' in the app).

There likely is a PC equivalent (if not there should be) but I can speak from personal experience that the iPad implementation of this app is a dream come true for a 3-ring binder user for worship team playing. Worship team playing is kind of a unique 'gigging'. You play 4-5 songs max per week. You have about 1.5-3 hours to learn how to play off each other (our overall team is probably 20 people, with 5 or 6 together at one time) and set mic/signal levels, and you are not expected to repeat songs that much - maybe one 'theme' song that you do for a few weeks in a row. With our team, we try to keep the song list fresh; very little recycling goes on. The 'standards' get re-arranged and orchestrated and quite honestly end up being new songs - different than jazz and rock standards that are expected to be played in a certain way and are played in a 15-20 song set, rather than the very short set I mentioned above.

The time crunch almost demands 3 ring binder use. It's one reason OnSong is so cool for this.

iRealbook looks very similar and it runs on Android - You might be able to get a cheap Android tablet to do something very similar. Keep in mind that you don't need a full chart with OnSong, a couple lines is all that's necessary if you trust the flow control. I can't tell if that's an iRealbook feature or not - it's not highlighted on the website.
