This is a take on how my productivity is going with carrying 2 devices every day, NetBook and Laptop.

Yes its painful to carry 6-8 KGs everyday.. But there are benefits. I am using my everyday laptop as a mini datacenter with all san and cluster simulation and NetBook for everything else, its more like a 8.9' Mobile Phone..

Upgraded NetBook memory to 2GB and SSD to 64GB.. It now brilliant with Windows 7 professional. 

Laptop with 8GB RAM and 1TB HDD running Windows Server 2008 R2 + Hyper-V + iSCSI Targets.. Bloody brilliant!.. 

Very soon I will need to replace my NetBook with a tablet model. Not much models out there for a reasonable price..

Some references I found for NetBook with a tablet model...
