No, it is n't. Eclipse worked well on my four year old, 2GB Macbook. Now I've added 2GB of memory, it runs phenomenally fast and it is rather nice to have a true UNIX (BSD) underneath and all the mainstream scripting and programming languages, LAMP etc. there without having to scrounge around the internet and hope I've got a compatible set of libraries and tools. I have got an old Thinkpad, that I greatly appreciate; but speeds are not comparable and the last time I tried to update the Linux installation (UBUNTU, automatic) on half of its disc space, it refused to boot into Linux again and, having got OSX/BSD on the mac, I could not be arsed to sort it out.
I've worked on (and still do) almost every variety of Linux, most UNIXes, including several BSDs and a couple of other operating systems. Spare me the vagaries of the average Linux/GNU release and the time wasted seeking and installing the necessary software (yes, I know about the wonderful interfaces now and the automatic updates; but too often they feel and work like bodged-on afterthoughts, with the command line versions being even worse). Of course, one can pay Redhat, SUSE and others for a proper release with some support; but even then there are oddities and then this "free" OS is not so free. Odd: it's so good Dell and others are remarkably reticent about their Linux offerings, despite the "consumer" programmes (word processors etc.) becoming almost acceptable. My employer (many thousands of servers, virtual and physical around the world) is moving to Redhat. Not bad; but response time, reliability, blade servers etc. make the old Solaris systems look rather wonderful. Sometimes, the network services make paint drying seem like Formula 1 and almost make me like Windows, almost.
As for the Google Chrome idea of a laptop that needs the network to say, "Hallo world": I travelled with a friend across various parts of Europe, lugging his Chrome machine (present from his loving, "techie" son) and experienced the delights of being unable to install Skype in any form, total uselessness when away from a wi fi service etc.. My mobile was more useful, infinitely so. Yes, it is an iphone. But even his ageing Nokia "smart phone" was more useful and has a decent camera to boot.
