Tyson Stevenson with WebProNews has published a good “intro” article to Tablet PCs. What I appreciated most was his closing comment ( which I totally agree with BTW):
Are they future proof? Till recent years the Tablet PC was a commercial failure but with the advances in battery technology, handwriting recognition software, wireless internet access, larger memory, better screen resolution they are being accepted as commercially viable option. Many popular science fiction movies portray the use of Tablet PCs. Tablet PCs are bound to replace the notebook & pen and future books, magazines, newspapers.
I’ve said it before and I’ll say it again: it’ll take time, but we will see all laptops contain tablet pc functionality.
