I am in a country where a laptop and broadband is a luxury. I was privileged to own Logos 3 and a laptop albeit with much difficulty. Come Logos 4, and my laptop is not very usable with it. I appeal that rather than taking the approach that in an year or two, computers will have relatively higher sizing and poor performance would be better tolerated, I appeal that Logos be sensitive to their customers and try to painstakingly optimize Logos 4, much like what Microsoft did with Windows Vista. I hope the readers and logos would be able to appreciate what I am saying.
