Although I agree that VDI is becoming more popular there is still a fundamental issue that will either be the success or failure of this offering: price.
The biggest challenge companies' face today, like ours, is how to deliver a virtual desktop service at a cost effective price comparable to a traditional desktop or laptop.
Most financial managers who are forecasting and budgeting the bottom dollar do not care about the long term saves in OpEx (Operating Expense) they are focused on the saves they can show today. They don't care about the long term labor savings; maintenance cost avoidance and upgrade expenses. They need to show that they pay $1200 for a laptop today but tomorrow the cost for a VDI will be less than $600.
This is an interesting topic and I will be expanding on it in my blog in a few short weeks after I complete some additional fact finding for my own company's offering.
I was wondering if you ever did expand on these thoughts as you mentioned in your blog.
