why not go wireless now? It's cheap, easy and far more flexible!

As explained in another post, there's always more effective capacity
for shifting signals around if you actively guide them (through cable)
than if you radiate them through free space (even if you try to do it
directionally). There'll always be an economic tradeoff between fixed
wiring (higher up-front cost, larger ultimate capacity, cheaper
interfaces, longer-lasting infrastructure) and wireless stuff (less
up-front cost, incremental cost greater, data rate limited to whatever
you buy first time round). It's naive to suggest that fixed copper/fibre
is going away any time soon. For home use, many may find wireless more
convenient; but it's kinda self-limiting, as more and more devices
crowd into that little bit of "no-license-needed" spectrum around
2.4GHz.
