Quoted: But imagine if you could get online anywhere you liked — in a taxi, on the beach, in a hotel with disgustingly overpriced Wi-Fi — without messing around with cellular modems. What if you had a personal Wi-Fi bubble, a private hot spot, that followed you everywhere you go?

Incredibly, there is such a thing. It’s the Novatel MiFi 2200, available from Verizon starting in mid-May ($100 with two-year contract, after rebate). It’s a little wisp of a thing, like a triple-thick credit card.

Just got this and will be trying it out on an upcoming trip. Looks well made and comes with a semi-hard travel case and a flat, roll-up Ethernet cable.

About the only disadvantage from what I can tell is that it can't connect to an encrypted WiFi connection for the purposes of establishing a wired connection to a machine. This is not a scenario that I personally need.

Minor nit: Since I always have an Ethernet cable in each of the two bags I carry my laptop bag in, I don't need the roll-up Ethernet cable. But, if I leave it out, there's empty room in the travel case, which could possibly lead to it being crushed.

UPDATE: I'm very happy with it. It even subbed in my house when I had to send in my "big" router for a warranty exchange. That did expose another disadvantage -- range is a bit weak, probably because it has a small, internal antenna. The laptop card may matter too. A current card had no problem connecting at 60 feet away, while an older A/B card was unable to connect at 30 feet with just one wall in the way (both cards were internal to the laptops).

Quoted: The Linksys Wireless-G Travel Router with SpeedBooster lets you carry a wireless network wherever you go. There's a built-in access point, which lets you connect SpeedBooster-enhanced and regular Wireless-G and Wireless-B devices to the network. There's also an Ethernet port to connect your wired PC. The Router function ties it together and lets your PCs share a wired or wireless Internet connection.

The travel-friendly form factor includes a built-in power supply and antenna--it even comes with a travel case! Create a temporary, personal, wireless access "bubble" in your hotel room. Just plug the Router directly into the wall, and connect the hotel's fast Internet service cable. You can also create a shared-access bubble attached to a wireless Internet connection to use multiple devices on a single hotspot account in a coffee shop or airport lounge.

To protect your data and privacy, the Wireless-G Broadband Router can encode all wireless transmissions with WEP or extra-strength WPA Personal encryption. The Router can serve as a DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with the web browser-based configuration utility.
