Wow. When I wrote about Palm’s Pre Plus on Verizon one month ago, it was $150 (after a $100 rebate) on a two year contract, and the Mobile Hotspot feature was $40 a month. Now the Pre Plus is $50, and Mobile Hotspot is free. (The Pe Plus’s little sibling, the Pixi Plus, is $30.) The price cuts make the nifty Pre Plus one of the best bargains in smartphones–maybe the best buy.
