Re: Why not a tablet?
Just like a notebook gets carries around in a notebook bag many tablets are used in a book-case. And those have the stand (if needed) included. Some others like the Surface have the stand in the unit itself. I.e the Note 10.1 and it's soon to come replacement Lenovo TPT2 have such a case (add on) as did the EP121 (part of the package)
If I am browsing on any of the above I write mail with the WACOM stylus and let Windows (1) translate it. No need for a keyboard for what I do without a table. Works fine in the lap or the cradle of the arm. Telling the unit what to write also works for the EP121 (Nuance Dragon Natural) and likely will for the TPT(2). Windows internal speach recognition is also nice. Granted speech is not a tablet-only feature.
Tablet PC are smaller/lighter than a similar powered netbook/ultrabook if I do not need the keyboard. And 90+ percent of the time I do not. I do keep a BT keyboard in the attache case (or the notebook bag in case of the EP121 since that needs a charger to get over the day - TPT2 won't). And for most browsing/media consume stuff I do not need the keyboard.
Add in that Windows has software (as part of the OS in MS Journal, Part of office in OneNote) that can translate handwriting into text in a "batch mode" so I can even write lengthy concepts in handwriting and tell Windows "translate the stuff" when I am done. Depending on your handwriting and what the stuff is needed for simply mailing the draft around often is enough(3)
Same for check-reading documents in Word, Powerpoint or PDF format. The software supports hand written notes and handwriting->text. Where once before one would print out stuff and use colored markers you can now use a tablet pc.
10-13'' tablet pc are similar sized to a sturdy legal/A4 pad or writing board and can replace it if you have good, mature software for it. Windows does tablets since XP and the software is extremly mature, stabel and capabel.
About the only thing I do NOT use - is touch. One of the "not good enough" criterias on the Note 10.1 was that touch could not be completely switched off. Palm recognition on Wacom is good but not perfect (and eats cycles).
(1) Or Android but HWR there is Win-XP level currently
(2) The S10-3 could run Dragon at high CPU load
(3) Everyone uses Windows around here anyway
