After almost 3 weeks (and lots of late nights), my experiment with installing another Linux distribution for my Asus Eee 900 netbook has more or less come to a conclusion. After numerous installation (Ubuntu, Mandriva, etc), countless reinstallation and testing, I'm settling now with Mandriva One.
I had never spend so much time just on a single objective. Through it all, I must say that at least I had learn a lot more about Linux, beyond the little I had to do sometimes in my work with Unix. Linux on the client is not for the faint of heart. One can easily break the OS from all the hacks and tweaking. I can understand now why Asus's provides little option for changing the delivered Xandros OS. With different kernels, distributions, package managers, windows managers, one wonders if having so many choices (each with their own issues) is such a good thing.
What I have learned from this experience is that tough as it may be, Linux can really be a substitute for MS Windows if you are willing to spend the time learning how it works. Every application I have on my Windows PC has the same or equivalent Linux counterpart, including My Dropbox and Skype, etc. The only application I could find for Linux is the PCSuite for my Nokia phone. Hello Nokia?
