Thanks for the feedback on Windows 8. Although I realize that touchscreen gestures on Windows 8 can be done on the touchpad as well, I've read that laptops without a touchscreen can still be a little awkward to use. Have you had to use any Windows 8 machines without a touchscreen? Curious to know what the experience is.
Nope, I haven't upgraded my Windows 7 devices (both of which are non-touchscreen computers, one desktop and one laptop) to Windows 8.
Admittedly, I like Windows 8 and the Metro/tile interface a lot, so I'm not the most unbiased person to ask about Windows 8. Having said that, I would say Windows 8 works very well via touch, probably works very well via mouse, and merely well (as opposed to very well) via trackpad. There are certain features in Windows 8, like accessing the Charms bar (i.e. the control panel bar hidden on the right side of the screen) and especially closing apps that are easier to do via touch or mouse than they are via a trackpad. But even in those cases, performing those functions is no harder than it is in Windows 7 or earlier versions of Windows; they are just done differently. (With the Charms bar, which is used in both Windows 8 Metro/tile mode and Windows 8 desktop mode and essentially replaces the Start button if you don't want to perform a "just type" search*, you put your cursor in the upper right corner to bring up the bar rather than clicking a start button in the lower left corner. With closing apps, you place the cursor in the top middle of the screen and when the hand icon comes up, click and pull down to the bottom of the screen rather than clicking an "x" in the application's screen in the upper right corner.)
For whatever it is worth, I'll note that I have both a Windows 8 touchscreen laptop (the Asus VivoBook X202E, an 11.6" laptop with a 3rd generation Core i3 processor that costs $550 at most retailers and $500 at the Microsoft store; the VivoBook Q200E that is being sold at Best Buy right now for $450 has a 2nd generation Core i3 processor and is a slightly lower specification version of the VivoBook X202E) and a Windows 7 non-touchscreen laptop (the HP Pavilion g4-1215dx, a 14" budget laptop with an AMD A4 processor that was released in October 2011 and cost $350 to $380 at Best Buy); I bought both of these computers within 2 1/2 months after they were released. Both of these computers are budget laptops; the price difference between the two when each was new was probably mostly due to the fact the VivoBook X202E has a touchscreen (though to be fair it also has a smaller screen). With the Pavilion g4-1215dx, 2-finger scrolling works very infrequently; I almost always have to use the right-side scroll bar to move around on a webpage or in an application. By contrast, with the VivoBook X202E 2-finger scrolling works very well once the computer is fully booted up (after the Metro/tile start screen comes up, some processes, I think related to the Norton Web Security I have installed, need to run for 30-60 seconds). The 2-finger scrolling works in both Metro/tile mode and desktop mode. Also, pinch to zoom also works well on the VivoBook X202E (maybe too well; I was inadvertently changing the zoom scale occasionally while working on a Word document earlier today); I've never been able to pinch to zoom on my Pavilion g4-1215dx.
Stated more simply, using the trackpad is a lot easier on my Windows 8 laptop than it is on my Windows 7 laptop.
*The "just type" search function in Windows 8 Metro/tile mode is a genuinely great feature. To access it, just click on the screen anywhere not in a tile and start typing whatever it is you are looking for. The Charms bar will come up on the right side of the screen and show you how many applications, files, etc. match the name of whatever it is you typed. This feature doesn't just work for items on your computer though; you can also search for applications in the Windows app store this way too by clicking on "Store" in the Charms bar. Actually, I think you can also search within installed apps, like for example eBay, using the "just type" feature; I haven't tried to do so but when I have done a search via "just type", I've noticed eBay and other installed applications will also pop up as choices in the Charms bar. The "just type" functionality in Windows 8 is an awesome, awesome feature IMO, probably the best feature in an operating system that I think has a lot of really good features.
