I carry my SP in a Logitech case about the size of a kid's lunchbox. It holds the SP, power cord, stylus, 3 in 1 usb cable, usb mouse, and a usb pig tail dock usb port extender, Jambox, and an external microphone. Since I always have a mouse with me, I continue to use Chrome as my browser. Firefox when I want to download youtube videos, and IE only because it is pre installed on the Pro. The setup allows me to use the Pro almost exactly as I do at home with an Apple Bluetooth keyboard, a 27 " monitor, and a Logitech speaker bar.
Just for my interest: I don't see the advantage of using touch controls most of the time, particularly if I have a cheap, lightweight mouse easily available. Touch controls are too inaccurate to be useful except for large screen shifts like page scrolling. A mouse allows letter by letter selection, almost pixel by pixel selection in pictures, and is enabled for 100 % of Windows programs already. Touch enabled requires a separate version, as far as I can tell. I mostly use touch Kindle and touch Evernote, both of which work fine unless I am trying to edit letter by letter or hit a particular close gadget or minimize button. Touch has a long way to go before it is even half as useful as mouse control, in my opinion.
Yeah, except I would have said "a long, long way to go . . .." (maybe another "long") Touch is fine for reading (Kindle) and browsing, but not for actual working -- at least not for me. I always keep a mouse handy. I use the MS Wedge mouse. It is small & bluetooth. If I'm carrying the Pro with just the TouchCover (almost naked), I usually just put the Wedge mouse in my pocket.
