38. Conclusion – Which is Right for Me?
• A Few Questions to Ask Yourself:
– Do virtual desktops still make sense for you?
– Do you already have one of these vendors in
your environment and have experience with it?
– Is there a particular feature that is very
important to you available in only one of the
vendor’s solutions?
– Are you already partially or fully licensed for
one of these solutions?
– Do you have in-house expertise or a qualified
partner to help you with the solution?
