SharePoint 2010 is one greedy beast and you can’t settle with your plain old laptop; first of all you need a x64 bit environment and second of all you need some RAM. Developing for SharePoint 2007 required just a 32-bit machine, less than 4 gigs of RAM and Virtual PC and you could do most of your work without complaining to much. SharePoint 2010 requires some more thought through development environment .
About two months ago I tried to reach out to the SharePoint community with a small survey on how Virtualization is used with SharePoint. The survey was primarily for my own interest to benchmark what others are doing, but I also thought that I should share this with everyone. SharePoint and Virtualization is an interesting piece of discussion; some despise it and some love it. For more information on SharePoint and virtualization read this great article from SharePointMagazine.
Windows 7 has an upgrade to Virtual PC which allows you to run Windows XP applications virtualized on your Windows 7, without having to run the whole desktop running. I still have to use Visual Studio 2003 to support some old good applications including SharePoint 2003 apps. So I have used a Windows XP virtual machine to run it, but now I can fire up Visual Studio 2003 directly from my Start menu in Windows 7.
The day has come when Microsoft officially started to talk about the next version of Office 2010 clients and SharePoint Server 2010 (no longer Office SharePoint Server). We have since some time known that SharePoint 2010 will be supported only on a 64-bit platform, just as Exchange 2007. The new stuff revealed yesterday (as preliminary) are that not only is 64-bit required, it will only be supported on the Windows Server 2008 64-bit platform (including R2) and it will require that you have SQL Server 2008 on a 64-bit platform.
