Most of these things you're talking about use switching power supplies. Generally it doesn't matter if the input waveform is a pure sinusoid or modified sine- the first stage of a SMPS is a rectifier and filter capacitor that converts the input to DC anyway.
I've never had any trouble running various electronics off modified sine inverters. You'll be losing some efficiency and thus battery runtime by using the inverter and individual equipment power supplies. But you'll have readily available off the shelf parts, and an easy to understand/repair system. Your call on the tradeoff.
