Is having Wi-Fi cheaper than routers for a desktop?

I was sitting here thinking to myself that while I game a lot, a laptop would be a much cheaper way rather than having five desktops in the house. Like you could take away Internet on your iPhone due to the fact of having Wi-Fi, then you could get my dad an iPad like he wants, and I could have a laptop; and it'd just be paying for that one Wi-Fi source rather than all the plugs in the wall for multiple plug ins.Am I right or am I wrong? I'm not that skilled in the Wi-Fi department, meh.

Personally, I'm a big fan of the Wi-Fi. You can buy Wi-Fi routers relatively cheap, and sometimes even get one at a reasonable cost from your ISP (mine came with my service package for no extra cost).In addition, you can buy a USB dongle that will plug into your desktop or buy a wireless modem, which will allow you to enjoy the benefits of a wireless connection with the gaming power of your desktop. I'd say it's a worthwhile investment.

  • Would this be cheaper than an iphone plan? I have an iPhone 5 and I don't have a sim or plan with it. Could I just carry a mobile hotspot with me instead of getting a $100/month plan? If so, what carrier has the cheapest?
  • Will it be cheaper to pick up instead of having an upgrade shipped to you on Sprint? I'm eligable for an upgrade, I'm looking towards a new iPhone 4S on Sprint for $100 but when it comes to taxes it brings it up $55 more. And that goes by zip code. So is it cheaper if I can put an in store pick up? Will it be 100$ like it says if we picked it up at the store?
  • Will I find the Apple iPhone 5S anywhere cheaper than $869? I'm wanting to know whether the new Apple iPhone 5S will be sold any cheaper than Apples price, which is $869? Will it be cheaper at other retailers? Or will it be cheaper online off Ebay? Broken down my question is, Will the iPhone be sold anywhere cheaper than the Apple Stores price? Thanks! So pretty much all stores will have the iPhone5S for the same price of $869 when the phone comes out?
