Have a look HERE I use HP for everything I need.

tl;dr

No "XP Mode on HP" You can always run VM software.
No Network Backup settings LOL
No Domain mode http://windows.microsoft.com/en-us/w...res/networking

I do not think you will need Professional for those reasons. However, I am in no way a developer so someone else may want to chime in.
