4 years ago I would have agreed with you whole-heartedly! I loved my Toshiba Portege with a 12" 1400x1050 screen. It had high pixel density(140PPI) and a 4:3 aspect ratio. However, with the ability to snap a window to half of a screen in a lot of modern window managers widescreen is not so bad as long as you have a greater that 1000 pixel vertical resolution.
I find myself using virtual workspaces much less than I used to because of this. In light of this I am more disturbed by the stagnation of pixel density advancements than the prevalence of widescreens on laptops. I mean... We now call 768 vertical pixels HD no matter how big the screen. How is that high definition on a 15" laptop? Especially when the taskbar, menu bar, status bar, etc take up 30 pixels each!
