I questioned the RAM when we got our Versant 2100, 4 gigs is not a lot especially with it being a cheap and easy upgrade. They stated the computer was made for it and that was all I would need. I have contemplated throughing more RAM in, but not sure it it will make any noticeable difference so just leaving it as is.
I would love to see them move to an SSD rather then a standard hard drive, would make a huge difference just starting up and loading and anything that is accessing the hard drive.
You must have got the EX. The EX-P has 16GB. I am surprised the EX only has 4GB though.
