I just got my first HP Mini wireless note pad. It seems to work great, but I wanted to know, when I am traveling and just want to be alerted when I hit a hotspot, without leaving my note pad turned on if there is such a thing as a handheld or portable wi finder with a audible alarm and where would I look. I tried Staples with no luck at all. I saw one advertised on TV for 14 bucks, but figure I will get screwed on something sold on TV only and that cheap. What is available and where do I look? If you have one you like, let me know all about it please. Thanks
