You are probably way ahead of me on this but, preparing against the day when my ancient 600E ThinkPad finally gives up the ghost, I have been casting an envious eye over the latest and greatest. LED backlights appear to be the way to go but one negative I have noticed is the rush to widescreen displays. On the premium models there is no issue but a number of lesser models "feature" a relatively low vertical resolution.
One that caught my eye is the Sony VAIO VGN-TZ11MN, which isn't exactly cheap. Drop dead gorgeous, small enough to be truly portable amd with an LED backlight behind the 1,366 x 768 screen.
Whoa, 768 pixels high.
That's no better than the 1024 x 768 of my 9 year old ThinkPad.
Given I have no interest in viewing movies on a notebook (and I accept that others might want to) and that the amount of vertical screen real estate taken up by menus and toolbars in a number of image editing programs results in an effective 16:9 usable area left over on a 4:3 screen I wonder whether widescreen displays are that useful unless one can run to a 1,920 x 1,200 model.
