I use a PC 8-10 hours a day at work, mostly in a docking station with dual 24" displays and a full keyboard. My home laptop is waiting for Dell to visit for second time in two weeks and I've been wanting to get something slimmer for a while anyway so that might be a sign now is the time. I've kind of narrowed it down to a Dell XPS13 with touch, a Microsoft Surface Pro 3, or a MacBook Air. The Dell gets great reviews but on my list gets dinged for the poor service on the current machine, though long term I've had good luck with them. The Surface the huge pro is tablet mode and the pen, but gets dinged on my list for its keyboard and the kickstand configuration which some reviewers say makes it less desirable as a lap-top laptop and I use it in a recliner quite a bit. The MacBook of course is a whole different ecosystem, plus the comparable machine to the other two only has 4GB of ram and no touch screen. The pro of course is the legendary service. It seems like the other Ultrabook options are not i5's which is why I've pretty much focused on these three options.
My primary uses will be web browsing (Google Chrome either way) and Microsoft Office (mainly OneNote and Excel) which used to be a ding for the Mac but Office 2016 is now out for Office 365 subscribers for the Mac and seems to get good reviews. OneDrive would be my cloud service of choice since I have 1TB of storage there with my Office 365 subscription.
So question for those that switch between PC and Mac--do you find it frustrating to change OS's day and night? Changing my Day OS isn't even remotely an option before anyone mentions that.
