I wish the tablet/laptop convertible had caught on for exactly this reason. They've gotten somewhat better over the past 13 years:
Acer Travelmate C100 (2000) -- the first tablet convertible, shipped with "Windows XP Tablet Edition", which was difficult to find otherwise. - http://www.cnet.com/laptops/acer-travelmate-c100-tablet/4505...
HP Pavilion tx2500 (2007) -- a recent tablet convertible that could almost be viable today. The pen input was amazing to use in Office and other places. - http://www.tabletpcreview.com/default.asp?newsID=1217
Microsoft Surface (2013) -- The big update here is making the keyboard detachable, instead of swiveling under the monitor. I still count this as a tablet convertible. - http://www.microsoft.com/surface/en-us/surface-with-windows-...
