Right now you can get the Galaxy Tab on contract with T-Mobile for $350. That is an extra $50 off for those keeping track at home. This might help you bite the bullet this holiday season and pick up a Tab for you and the family. Order by December 20th and receive free overnight shipping as well!
The two plans you can choose from are for 200 MB and 5 GB for $25 and $40 a month respectively. If you plan on viewing more than the occasional web page on the go, then grab the 5 GB plan. You get over 25 times as much data for less than half the price.
