with the full processing power, heat, noise, etc of the laptops of the day.
This was where they failed for me. I had a couple different Fujitsu Stylistics, and overall I loved it. OneNote was great for notes, and had pretty decent handwriting recognition. I could run any Windows application, and overall it did great. I could sync notes across devices and access them anywhere. It was pretty impressive stuff for ~2000. But the big downfall was the jet engine fan and battery life. I'd be in a quiet classroom or office meeting, and the fan would kick on. I'd get That Look from people and it got old. I also usually only managed to get 2-3 hours out of it, although I did have a spare battery I'd carry around for it. I usually had enough juice to last a whole day of college classes, but sometimes not.
It'd also get pretty darn hot when I was doing anything that ran it very hard, but note-taking didn't usually do that.
