I'm toying with the idea of replacing my ageing Dell XPS (M1530) with a 13" MBA (128GB - about as far as my limited budget will stretch), because it's smaller, lighter and looks fantastic 
However, I occasionally use my laptop for a bit of dev work (.NET, MSSQL) which is obviously an issue under OSX.
I'd therefore either run Windows under bootcamp (which I understand is dual-booting?), or virtualised under something like VMware.
Just wondering if anyone does the same, and whether it's a workable solution? I'd either run the VM from the SSD, or from an external disk.
