This may not be a big deal to anyone but me, but I've just gotten a few 8-port network switches, which have FINALLY allowed me to expand my LAN. I'm now able to light up all the network sockets in the house and I can connect all the computers and printers to the LAN at once.
This is an incredibly busy summer, between my day job and a bunch of other things. But I'm feeling fairly happy about everything. :)
