Hi, I currently have a mid 2009 intel core 2 duo MBP with SSD and 8GB RAM. I have Parallels open during the work day using Visual Studio 2010, SQL Server 2008, etc. The current setup handles this real well. But I'm travelling a lot these days and would prefer the MBA's form factor. If I get the MBA 2011 i5 (faster processor) but half the RAM (4GB vs 8GB), will I notice a downgrade? Is anyone here using MBA with Parallels and Visual Studio programming? I've done tons of search on google but I am unable to find someone who is using this in the real world. Thanks in advance!!
