Look at the a2sd feature some have - unlike the older app2sd which moved some bits of the programs to the microSD card, this uses links in the Android *ix filesystem to move the whole lot to the card.
I have far more installed than I ever did before, and currently have (looks) 36Mb of free space left, plus 110Mb of cached data on the internal storage.
This plus the N7 has totally cured my desire to get a new phone. YMMV.
