TiPb.com compares using Android WiFi tethering to power the iPad against paying extra for the iPad 3G.

Our friend (frenemy?) Rene Ritchie over at sister-site TiPb has done a quick, largely (and admittedly) unscientific comparison of connectivity options for the iPad, and whether the additional $130 for the 3G model and corresponding data plan is worth it. In the test, he pits the built-in 3G over the Rogers' 3G 7.2 Mbps HSPA, WiFi tethering on a Nexus One running Froyo over the same network, and a Verizon Palm Pre Plus roaming on the Canadian Bell CDMA network.

Results were varied, but in the end the conclusion was just as you might expect: for the most convenience, shell out the dough for the 3G model and plan; for savings, use your Android handset's built-in free WiFi tethering (where available), or your carrier's paid solution.
