I am just in the middle of the preparation for the events I will be having in the next weeks and months and I am totally amazed by my new machine. I opted for a DELL Latitude E6500 with a Solid State Disk and I am just amazed… Opening times for Visual Studio are close to nanosecond (ok kidding but it is amazing). If you are deciding for a new machine, I would recommend to go for such a disk… It is definitely worth it!
P.S. I am running Windows 7 in production on this machine as well for over 3 weeks now and it rocks!
