Just when I was losing to the idea of configuring my macbook for dual boot (or even getting a new machine) to be able to use Windows XP with more ease.

I am using Parallels to be able to do testing of the apps I’m writing on IE (one site I’m working on has more than 1/3rd of users still IE6…) and to be able to recompile and package an old J2EE application using a proprietary framework and builder that works only on Windows :-(

Until upgrading to Parallels 4.0 (which I did yesterday), generating the EAR for said application was taking more than 25 minutes, now it’s just down to less than 5 minutes! The big improvement seem to be in the (shared) filesystem access but also everything else seems snappier and the VM feels lighter on the system.

Overall a highly recommended upgrade to anyone using the product.
