I'd assume most standard computers today have between 6 to 8 USB ports. Also you can unify alot of your USB devices these days or is that just Logitech wireless products?.
My wireless keyboard and mouse use 1 USB port (but alot of batteries
), then i got Logitech 3Dpro and TrackIR, I dont have rudder pedals, So i'm only really using 3 USB ports to flight sim.
The only other USB devices i have plugged into PC are a Charging dock for phone/PS3 pads and a USB Airfreshner. If i was to add Rudder pedals to that i'd hit the 6 USB limit that some computers have as standard. however the airfreshner is a optional device lol.
So taking out the airfreshner and putting a tablet in there permanently would mean we lose some of our control devices, but disabling the tablet in devices should automatic revert back on newer windowed systems or am i wrong. lol
Don't worry i have 10 USB ports so the airfreshner can remained plugged in, So unless it breaks there isn't a chance i'll smell out the forums lol
