Scott Hanselman har skrivit en del om hans tanker kring pekskärmar på bärbara datorer. Efter att ha testat det en längre tid för första gången skrev han detta.
TouchScreen
A touchscreen on a laptop? Why? What kind of madness is this? After using it for a while having a touchscreen is a nice to have. The mistake reviewers make is thinking that we the users are expected to be swiping around all day with tired gorilla arms. The real truth is that it's just a third input device. Keyboard, mouse, screen. Now everything can be touched - and preferably ordered like this by frequency of use, at least for a laptop.
I find myself reaching for the screen a few times an hour. Not enough to get tired and not enough to pretend I am on a tablet, but enough to appreciate it. Sometimes clicking Start and touching a large icon is just faster than the mouse and more relaxed than the keyboard. After a while I even used the taskbar buttons by touch to open apps as those buttons are just a few inches from the top row of function keys.
I often used the touch screen to position the cursor when editing large amounts of text. When browsing long form reading on Instapaper I would scroll with the screen, usually resting my hand in the lower right corner of the screen and scrolling with my thumb. It's a very natural position.
This reference hardware includes 5 touch points and built-in apps like Maps worked great. It did tend to miss some taps though, usually just one finger doing basic stuff. I'm assuming this is a hardware driver issue, perhaps trying to prevent unwanted taps. It was noticeable enough to be irritating so I'd recommend to anyone purchasing an Ultrabook with a touch screen to spend some time with the hardware and ensure it's consistent and reliable.

Don't knock a touchscreen until you've used one. Every laptop should (and will) have a touch screen in a year. Mark my words. This nonsense about how your arm will hurt assumes that you're only using it. A touchscreen is complementary not primary. I use it for pinching, for scrolling web pages, and for launching apps. It's much faster to just touch the icon than to mouse over to click one.

Nu har han ganska stark anknytning till Microsoft och kanske talar väl om det för att boosta Windows 8 och kommande PCs. Men bilden ovan som Apple visar med en rak arm som sträcker ett pekfinger mot en laptop tror jag inte ger en helt perfekt bild över användningen heller.
