I'm not sure I'd use a word processor as an example of a GUI application. The first word processors I used were character based (although not true command line). They were incapable of showing text in a format appropriate for the attribute applied. That didn't stop them from producing documents that contained multiple fonts, italics, bold etc. They simply tagged anything that was non-standard so that you could see that they had an attribute applied. Now WYSIWYG was clearly a step forward but even a modern word process isn't really that much different to the character based processors I first used. Perhaps the only innovation present today that couldn't have been achieved would be to embed graphics and images.
As with other similarly minded people I've seen responses to, I don't see this as an issue regarding your choice of interface. I like GUIs. One of the biggest benefits I first got from such an interface was the ability to have far more terminal windows than I'd been able to use with a real terminal. Even today, I don't think I work so differently from the day I first got Windows 3.11 on my desk. I like what a GUI gives. I'm also prepared to consider that new innovations could improve the way I do my work. Certainly I use more genuinely GUI tools than I did with 3.11. The main problem I see, as has been pointed out, that these new GUIs are somewhat revolutionary. Gnome 3 looks little like Gnome 2. You could not say the same thing when transitioning from Gnome 1 to Gnome 2. I happen to like Gnome which is one of the reasons I adopted Ubuntu. Given what I've read today, it seems I might finally be convinced to go toward KDE as it provides an interface I'm more likely to be comfortable with. I've only just started using Gnome 3 but it does seem to be geared toward closing off functionality. Why for example would you want more than one terminal window open? Sure, it can do it with a middle click but why should the default behavior be to only allow one window. I'm prepared to be convinced. Smartphone interfaces are something I'm impressed with and happy to use. I just don't do the same things on my phone as I do on my workstation.
