Hello, I am about to send back my second 2010 MBA in 3 weeks (both were 2.13 GHZ, 4 GB RAM, 256 GB), after having owned a Gen 1 MBA. I am was hoping to be able to keep this replacement one I just bought, so I want to see if anyone here has solved this. Both MBA's had problems synching Office 2011 Outlook with my contacts on 2007 exchange server. MS is working on this issue now. There is a bug, if you have one corrupt contact Outlook 2011 just stops and thinks it's done and synching is complete and thinks everything is fine, causing many missing contacts. MS will give me a workaround by identifying the corrupt ones supposedly (work in progress, MS working on this for 4 days). The bigger problem I am having is my old MBA (Gen 1 MBA) charges my Blackberry through USB fine, however the new 2010 MBA doesn't charge my bberry. The Blackberry shows it's charging but after a while the "lightning bolt" (that indicates the bberry is charging) just goes away because the 2010 MBA stops charging the bberry. The Gen 1 charges it fine, with both (Gen 1 MBA and this new 2010 MBA) I am using the same USB cable and both have Blackberry Desktop Manger installed (which Mac needs in order to charge Blackberry). Anyone have any idea. I am wondering if they did something to conserve power and messed this up? I am going on trip and need to figure this out as it's the only way I charge my bberry. Besides having no backlit keyboard this new 2010 MBA has been a total hassle (this one and the one I just sent back)
