Hi McGruder.
I think it will be a good idea for you to pop over to Garmin's website and read their page about
"What is GPS?" Please do that before reading further.
Okay, now that you've read that, you might find it useful to go back and re-read my previous note to see if it's any less murky.
Now some basics about what you need in order to do what you want.
The laptop: You already have an idea what you want. Since space is no object you won't need to make any specific compromises for either motorcycle use or GPS use.
There are lots of forums to help you choose a laptop computer. So the only thing we need to add is, make sure it will do wifi if you want to be able to do internet when you are stopped somewhere that has wifi access. And to make sure that it does Bluetooth if you want to use any Bluetooth accessories, like a Bluetooth mouse or Bluetooth GPS receiver. If you don't know what Bluetooth is, look it up on Wikipedia.
When I say to make sure it will
DO wifi and Bluetooth, don't get suckered by stickers and promotion that say "Bluetooth Capable" or "Bluetooth Ready". That is an almost certain sign that it will not actually
DO Bluetooth without you purchasing and adding something else on. Same thing applies to wifi. You need to ask specifically if you can take it home, turn it on and it will make wifi and Bluetooth connections without having to buy anything more for the laptop.
Adding GPS capability to the laptop: You will need a GPS software program. You will see lots of them listed on the forum home page here, with reviews and dedicated discussion sections for each of them. These aren't all of them but they are the most popular and readily available for the average consumer.
You can use all of these products, to a greater or lesser degree, for travel planning, similar to the way you would use paper maps. Except that these products will calculate routes for you and display them on the map. They will also let you do searches for city names, intersections of streets and/or highways and for street addresses. They will also let you search for points of interest (POI). These are things like stores, gas stations, movie theatres, restaurants, hospitals, police stations, malls and so on. Most of these software programs come with maps that include millions of POIs in North America.
Some are much better at this than others. Probably the leading ones for trip planning, both before and during the trip, are DeLorme Street Atlas, Microsoft Streets & Trips and Garmin Mapsource. Street Atlas and Streets&Trips are incredibly cheap for what they do. Mapsource comes free on every DVD of maps that you buy from Garmin.
None of these need a GPS receiver to be useful, as long as you just want trip planning with no navigation capabilities.
If you want navigation capabilities to help you get guidance from wherever you are to somewhere else, you still need a software program
PLUS a GPS receiver .. a device which receives the GPS satellite signals, decodes them and transfers the location data to the laptop for the navigation software to use to display your current location on the map screen.
There are lots of choices for GPS receivers to use with the laptop. Most work very well and are quite inexpensive ($30 - $75). Some software programs also come bundled with them. For instance, Microsoft Streets & Trips, DeLorme Street Atlas and Garmin Mobile PC all have software-only versions as well as versions that are bundled with a GPS receiver for a few dollars more.
The GPS receivers that are designed for use with computers come in two categories: receivers that connect to the computer with a USB cable and receivers that connect to the computer wirelessly, via Bluetooth wireless protocol. All of the software programs I mention in here will work with any consumer GPS receivers on the market.
Street Atlas and Streets & Trips will work for navigation use but there are programs that do navigation better. In particular, the onscreen map and guidance displays are better for realtime navigation guidance in some others than it Streets&Trips and Street Atlas. Garmin Mobile PC, iNav iGuidance, and MapFactor Navigator are three that have excellent map displays when navigating. But these three are not as useful for trip planning, before and during the trip.
Go ahead and browse through the review of the various products reviewed and discussed in these forums. Don't get distracted by the technical stuff for now. Just keep your eyes peeled for features that you think might be useful, or at least interesting to you. Then you can ask more specific questions that we can help you out with.
In summary, for trip planning and navigation you will need to add a software program to your laptop, like the many reviewed and discussed here, and get a GPS receiver to receive and transfer the GPS satellite data to your computer. None of it needs to be expensive.
Finally, I know this will probably get me some flak but none of these programs are particularly easy to learn. Most are fairly easy to get going with the basics, but if you want to get the most out of them you will have to spend some time with them, and probably ask questions here and/or on other forums that support them. The good news is that some of them have free trials for download (eg. Streets&Trips) and/or come with 30-day money-back guarantees (eg. Street Atlas).
