Several months ago, i've bought a Mini PCI 3G Module, branded as HUAWEI EM660 CDMA2000 for my Lenovo ThinkPad X100e.
Previously I knew that there is a single empty slot on the notebook's mainboard for a Mini PCI module. And also, actually I want to free-up one USB port rather than using an all-day-long attached 3G USB modem's dongle.
I bought it from Jakartanotebook, it was costs about $16 at the time.

Installation :
To install this module on the notebook is quite easy. I opened the bottom of the laptop (unscrew). The Mini PCI's slot is quite easy to find, it located next to the SIM Card slot.
Plug the modem module carefully, lock it with (two) screws. There are two cables from notebook, each color Blue and Red. Now connect the blue cable connector to the antenna port labeled "A" (mean Auxiliary) and the red wire to the antenna port labeled "M" (mean Main). Do a gentle tap to make sure the connector is attached closely. And lastly, I do inserting the SIM card into its slot.
Test Drive :
This modem does not require special treatment. And it was immediately recognized as Huawei E169/E620/E800 HSDPA Modem by Linux (Ubuntu) without installing any drivers.
On Microsoft Windows XP / 7, this modem is also 100% compatible with Mobile Partner application from Huawei.
So how about the speed?. Well the modem is pretty stable and fast, and a little to warm if you're on a high load (such as downloading or watching youtube), of course without buffering :-)
And this is the Speedtest.net result of this modem with AHA (CDMA, from Bakrie Telecom) card (4GB Unlimited Plan, bandwidth 600kbps)
At last, no more USB dongle attached :-)
