Then why not 3, or 4 or 5, you know where this is going
said by tschmidt:2) Does not cost much more then running a single line.
It costs double. Maybe if the two jacks are side by side then labor is a little bit cheaper, but material is double.
said by tschmidt:3) Some of us still use POTS.
Ever heard of wireless phone stations? You just need 1 outlet that feeds as many wireless stations as you want, placed ANYWHERE! It's magic.
said by tschmidt:4) If you use wired VoIP phone nice having a second jack for a PC or other computer. Eliminates need to have a switch and allows PoE.
You only need ONE VoIP device that plugs to the wireless phone station I mention above.
COUNTER NICK PICK!
said by TheMG:it is much cheaper and easier to run cable before the drywall goes in, so why not?
It's not the cost for THAT addition that is too much, but the mentality of it towards a house construction will apply to MANY other parts of the home. The "why not" applies to electrical, plumbing, insulation, etc etc.
Though I admit that getting network to every room isn't as an expensive superfluous addition compared to extreme insulation or electrical wiring (Like 1 circuit per outlet, oh wow!)
said by TheMG:Ultimately it is the homeowner's decision. Some people are perfectly happy with WiFi everything.
It's all about balance.
Wired for key spots (living room, den, whatever other room that isn't just a bedroom/toilet/kitchen).
Wireless to cover the randomly located networked device.
