We had another beautiful week in the geek neighborhood last week and it's time to run down some of the most important stories over the last week in this edition of the SlashGear Week in Review. Windows Phone 7 went on sale in the US on Monday. Four GSM only devices landed with CDMA phones not coming to the US until early 2011. A cool looking Mintpass tablet with dual-screens was tipped to land in 2011. The coolest feature may not be the dual screens, but the dual-boot OS that the tablet will offer with Windows 7 and Android.
