"I just got this modem from Amazon a few minutes ago, plugged it into my 2 g surf Asus Eee (which does NOT have a dial-up modem) Asus Eee PC 2G Surf (7" Screen, 800 MHz Intel Celeron Processor, 512 MB RAM, 2 GB Hard Drive, Linux Preloaded) Sky Blue set up number to dial, account number and password, and it works GREAT! No Linux commands were required... it just works! I am typing this review on the Eee through the US Robotics modem. Highly recommended for any Eee user that needs dial-up.

Update 7/29/08: I am typing this update on a MacBookApple MacBook MB403LL/A 13.3" Laptop (2.4 GHz Intel Core 2 Duo Processor, 2 GB RAM, 160 GB Hard Drive) White the modem works fine with it as well!

Update 10/26/08: It works fine on a MSI Wind as well MSI Wind U100-279US 10-Inch Mini Laptop (1.6 GHz Intel Atom, 1 GB RAM, 160 GB Hard Drive, 6 Cell Battery, 802.11 b/g/n+BT, XP Home) White"

"I run Linux (Ubuntu) on my laptop which means I need something other than your run-of-mill brain-dead Winmodem if I want to get dial-up working without a lot of hassle. I read the specs on this product decided to give it a whorl. Took the unit with me out to visit my folks (they only have dial-up access) got it working in minutes. Product was easy to configure, and nicely portable. So far I am very satisfied with this modem."

"Pros:
1. Small, convenient, takes up little room on my desk.
2. Vista compatible. That's rare, if my searches are any indication.
Cons:
1. Delicate. My first one quit in 2 days. (The company exchanged.)
2. Temperamental. Especially when hot. Try not to use for more than 5-6 hours, or it will simply develop static and kick you off line. It can even disrupt your landline service if plugged into the same UPS.
3. Once heated up, it takes hours to cool down again. "
