For this reason WxWorx is the only real option for full-time data. It's not perfect but it doesn't have to be. It gets the job done.
Dan hit the nail pretty good right there. WX-worx fills the gap perfectly. I just hope new technology doesn't make it pointless to purchase anytime soon. I guess if I was looking at getting it now I might be somewhat concerned the service will go bye bye as various wireless internet services come about. If that doesn't come to be anytime soon then I'd say it is a pretty decent tool/buy.
I just got it this last year and never once had to use my cell phone(except for the November chase as xm was turned off). I honestly don't know what else one would need if they had xm and a wifi card for their laptop. Wifi gets you all that important early stuff and then xm keeps you covered as you leave the localized areas with wifi coverage(or even a library). It is pretty nice not ending up with those excessive cell phone bills. What is better yet is not having ANY holes while you are out there. All my xm plan costs is $30 a month for constant data(imo there really isn't much need in getting the other packages for more). It is also nice not having to mess with it once it is on. This leaves no need to keep using the cell phone to see if something has gone up out of sight...you'll know right away. At $30/month and for what it does it seems silly not to have it along if you can afford the one time cost of the equipment(I got mine for $829).
All that aside I still keep asking myself if I should sell it, lol. With wifi and a decent cell plan you can have plenty of data to get the job done. I wouldn't mind having that $829 back for things, but at the same time it is pretty nice knowing you have info that you don't have to mess with and only costing $30/month while chasing now. So I guess my answer would be xm since I plan to keep it this year and have thought about selling it over and over. If I had other things I needed to buy and didn't have xm yet I'd certainly get the other things and just use the wifi stops and a decent digital cell plan.
