There are many ways you can go about this.
If you already have a cell phone with bluetooth, you could get internet service through your cell phone and using the blutooth to get onto the internet. So that means you will need a PDA with bluetooth to to connect to the phone.
Or better, get PDA with a phone capability (through your cellular phone provider?) and ask for the internet package.
It sounds like you like to surf the net, chat, check email, the typical net user. So you may want to invest on a foldable keyboard also.
My advice above where based on the assumption that you would want to access the internet even while in motion.
Other than that, just get PDA with WiFi; therefore, you need to be located nearby an open hotspot to access the internet. Unlikely you would want to have to go to a restaurant or a cafe to chat, you want instant gratification, so getting a PDA phone with internet service would be the most convene way.
I would like to buy a PDA (I think!). I have looked at several websites that sell them and I think maybe a few of the HP brand look good, but I am not a really technically savvy person. We (husband and I ) are not yet-retirement-age empty nesters, want to take several lengthy trips by road (in a small RV)through USA and Canada on and off for several months this winter. Normally I keep track of all our household and family matters (banking/bills/birthdays, you name it), plus we have 2 kids in college, and I would like to also be able to use MSN Messenger with them, plus I have personal and off-season business email I would like to check occasionally during these trips. As well I want to keep a detailed travel journal/diary. I ahve not heard of any kind of travel software for the PDAs but would be interested. I want to be able to plan our trip as it happens so I will want to be online checking check news/weather forcasts/maps/and maybe GPS info on the road (using hotspots maybe). I will not likely be using it as a telephone. Currently my very large purse is full little notebooks and papers right now, so hence the suggestion I get a PDA. Any advise as to the right one? Price is not a big concern, I am more concerned with being able to use it for the above purposes, be able to type on it somehow, and that it fit in to a mini backpack or normal size purse. Thanks in advance for any responses! I will be happy to report back on whatever I end up with. -Mrs. J.
