Running ESX natively on the laptop gives me the best virtualisation platform and full View feature support. These two machines can go in my cabin baggage, along with the other essentials for a five day trip to teach a VMware course. My choice is to run ESXi (part time) on my main laptop and use my shiny new netbook as the client.
Update: I have blogged about, for VCP training purposes. I wasn’t happy with either of these solutions mostly because i couldn’t use all of the RAM in my laptop and performance of nested VMs (in order to get PCoIP) isn’t very good. It’s possible to build a basic View 4.0 environment using VMs under VMware Workstation and a lot of people have already discussed the use of VMware Workstation or Player to run ESX in a VM.
