Is there any such device like a mini portable wifi gadget that exists? It would be nice to not have to depend on searching for free WiFi spots - which are very rare in my area.
Whilst I understand what you are looking for I think the only answer would be an iPhone or another cell phone which can access the Internet via the cellular network.
I really don't think you can buy a portable wifi machine because wifi is only an extension of a hard wired network.
... to all the people that say bring your laptop with a connect card...
if you had a laptop with you already, why not just use that to browse? it would be tons faster and easier to type, scroll, etc.
there really is no reasonable solution to this other than something that accesses the internet via cellular signals and whatnot.
But you can buy a portable "Wifi machine" it hooks up to a Laptop connect card as some of the cellular carriers call it, of Broadband connect card as others call it. It is a EVDO or HSPA (Evolution Data Only, or High Speed packet Access) device the best EVDO routers are made by Cradlepoint.
I think the OP is after something as small as and which can be directly attached to the touch and use ANYWHERE rather than something attached to a laptop. That's why I suggested an iPhone or other cell phone.
This is exactly what im saying about getting a USB EVDO connection card, and a EVDO Router. You don't need a computer at all, the router makes the connection to the EVDO card, and transmitts it to Wifi, and fits in the palm of your hand. It is battery operated, so all wireless (unless your battery runs out) and can plug up to charge
