My only concern now is connectivity . . . I'm just hoping it will work out in the middle of nowhere! (New Hampshire = mountainous nowhere land)
The price that you mentioned $425 -- is EXCELLENT for that computer. Probably up to about $500 is reasonable. I wouldn't go north of that.
I ... I apologize for not asking this a long time ago, but you said things like this several times and I let them slide, and I should've asked you about them before you bid on a computer. You've mentioned repeatedly that you're worried about the quality of the Wifi on the PB vs other Macs, since it has mildly lower range than, say, iBooks or Macbooks that have plastic casing.
To what are you planning on connecting? I'm sorry to ask a stupid question, but you understand at a basic level what Wifi is, right? Wifi is a short range wireless networking system. It only works over a couple hundred feet, and you really can only use networks to which you have access. So... if what you're talking about is, say, that you have a T-mobile hotspot account, a Macbook vs. a Powerbook might be the difference between accessing it in the parking lot vs. having to be inside the Starbucks.
A good notebook can access our home network from the street in front of the house, whereas a bad one would need to be in the yard closer to the house, right? But in any event, Wifi is generally a system that you use
indoors.... so the mountains outside don't really have any impact on your Wifi connection, as far as I know.
But it isn't like you can just drive around and get wifi in the middle of nowhere -- it isn't broadcast from cell towers or anything. You're not confusing Wifi with cellular data services (EDGE, HSDPA, EVDO, etc), are you? Those are the services "smartphones" use (iPhone, Blackberry, Treo, Q, etc). All those services are provided by cellular companies -- T-Mobile, AT&T, Verizon, Sprint, etc.
Those services
are broadcast using the cellular system of towers and satellites.
No Mac notebook to date has built-in cellular data services. You can add a card to any one that has a PC Card slot (PB 15/17") or an ExpressCard slot (Macbook Pro), or you can use an external USB one on any recent Mac. Depending on your cell phone and service provider, you can also use your phone as a modem (tethering, either via a USB cable or via Bluetooth, which is built in on most Mac notebooks, including all Powerbooks, later iBooks, and all current notebooks).
But just to be clear, without one of those solutions, you won't have access to the internet when you're in some random place or on the highway or anything.
