pajer- I looked that over from your reference but technically, it offers no more security than the freebie digiblur and I use, WEP 128 bit. For the price, they offer a different skin and some additional connectivity for tethering.
Others should check it out if they don't already have PDANet for their WM phone. For the ipad, the free ap works very well.
mestevo- If things go as planned we're going to be doing some traveling in 2 weeks. Now with having this wifi connection, I plan to make the trip without my laptop, just the ipad and my TP2 phone. I'm looking forward to the experiment.
I was concerned at being able to do some websites but I have tested all of them on the ipad I need to do and none use Flash, just java scripts. The most robust one was TD Ameritrade and it works great on the ipad. The other web application I had some trouble with was my security cameras. Turns out I was able to fix the issue with that by simply upgrading the firmware to use the new site that no longer requires Flash. So that leaves my former client's web design service. The guy was very insistent about the need to use Flash video but from what I understand they are having trouble with many non tech prospects due to having to add the Flash Plugin. Since this is advertising, using a format that people have to load something became an issue few tech people will understand. They are switching back to what I used now which is wmv video. Flash is great and I have it on my TP2 if necessary, but really, I'm surprised how little I suffer not having it on the ipad. YMMV, obviously.
One thing I would be interested in hearing from people who are using the ipad to do virtual desktop. I canceled my account with citrix so I can't test gotomypc but there are other free ways to do this but I will need to upgrade my PC to XP Professional. I plan to do that, which will allow me to do far more robust work whether traveling or at home from the ipad.
digiblur- I use a WRT 54G with 7 db antennas. The ipad's range with it is about 40 ft through walls inside the house. I've added a repeater with another 7 db antenna at 40 ft and now I can get good full signal into the back yard out to about 35 ft from the repeater using one antenna. There is a 3rd party software you can install on the Linksys that boosts the wifi transmitter power from the factory 23 mw, to about 100 mw. I have not used this as the 7 db antennas seem to be just barely adequate.
