I wrote back on November 23rd that according to EngadgetMobile.com it may be hard to find a Storm since they are selling out fast. The Verizon Wireless store today says:
Due to high demand for the BlackBerry® Storm™ 9530 smartphone, all orders placed today will ship no later than 12/15/08.
So, if you are in the market for a Blackberry and none other will do (at least if you are shopping with Verizon) you might want to choose from the Blackberry 8703e, Backberry Curve 8330, or Blackberry 8830 World Edition if you want to get it before Christmas.
Or, if you are shopping at AT&T Wireless (formerly Cingular Wireless) you might consdier the Backberry 8820, Blackberry Bold, or the Blackberry 8700c.
