The Springboard is a 7-inch tablet with a 1.2 GHz dual-core CPU, 32 GB of expandable memory, a 5-megapixel rear camera and a 1.3-megapixel front-facing camera for video chats.
The Samsung Galaxy Tab 10.1 needs no introduction, as it's already available at Best Buy and Verizon. It sports a 10.1-inch screen, a 1 GHz dual-core Nvidia Tegra 2 CPU and a duo of 2 and 3-megapixel cameras for your video and photo-taking needs.
Both the Springboard and Samsung Galaxy Tab 10.1 will support T-Mobile's HSPA+ fast data transfer standard.
T-Mobile hasn't announced the price for either device, but both should be available "in time for holidays" in T-Mobile retail stores and over at t-mobile.com.
The fate of Samsung's tablet, however, is slightly more uncertain, as Apple plans to seek a preliminary injunction to prevent sales of the device in the U.S. in just a couple of days.
