I suppose so
I've been using my Acer Aspire One for some months now and, as a portable bit of kit, I can't fault it. It was cheap, it is light (it's one of the SSD models) and it's fairly robust (given that I use it trackside at a certain short circuit, that has to be a given!) It's the first machine I've used in this situation that comes close to my long departed Psion 5 which was very light and small enough to slip into a pocket so that I could pretty much go anywhere with it. You can imagine, then, that the OS was not a primary concern here, though the heavily cut down Linux distro it was shipped with was soon consigned to history as I chucked openSUSE 11.1 onto it.
Not Windows? Well, no. Like I said, the OS wasn't a primary concern but I didn't want the extra cost. As long as it could do what was needed (mostly OpenOffice and the occasional Firefox session), Windows was just more money.
Not Ubuntu? No. Ubuntu (or more likely Kubuntu in my case as I much prefer KDE to GNOME or xfce) is fine but I had openSUSE to hand, plus I can see traces of the old "Linux is NOT Red Hat" story being played out in Ubuntu. I'm not a great fan of the latest openSUSE either (11.2 was released last week, yet el Reg never mentioned it once! Tsk tsk!) but 11.1 isn't bad; or at least it is good enough to have been installed on two of my systems.
In essence, I agree with Stuart 22 in that I believe that netbooks are slowly moving away from the market that made them, inasmuch as they are getting bigger, hungrier and more expensive. If things go on this way, I can see the netbook becoming indistinguishable from the laptops they used to undercut. And yes, you can blame the manufacturers for some of this, Microsoft for failing to address the inefficiency of their OS code sooner and the various Linux distros for failing to capitalise on a market that seems to have been made for them and, once and for all, kill off this image they have in the eyes of the farties of this world who won't touch them because they are afraid of the world beyond the reach of the Beast of Redmond.
It may mean that my little Aspire One (Reina to her friends) will be my first and last netbook. We shall see. Now I just have to get a coat with bigger pockets...
