I love my SP3, best damn device I've ever owned. I'm in sales and use onenote to take all my handwritten notes. Being as we are without a CRM I also keep a sales journal in onenote and basically handwrite almost everything. Being a roadwarrior there are numerous times per day where I have to log into our order entry system to check pricing etc. and with the SP3 no more pulling out the laptop as I have full capabilities with my SP3. I also use excel for doing all my expenses and mileage logs and it's all done with Office 365 and sync'd with onedrive back to head office. For a truly mobile platform where you need all the functions of a tablet plus the power and features only a laptop can bring, this is the device. So far I haven't found any limitations with the SP3 for me it literally is the perfect device. I've used 2 different Samsung tablets, multiple laptops and so far this has finally answered all my tech dreams. The icing on the cake is that I have a 1 TB hard drive full of tech documents and schematics and can plug it right in and email or markup whatever I need. Many times I've done all this sitting with clients, no more having to go back to the office! Then there is the entertainment side, I also have another jump drive with all my music, movies and tv shows for those endless hours trapped in airports or hotel rooms. As I said earlier...perfect device for me. The biggest plus is my backpack is tons lighter as I no longer carry two laptops and a tablet. One device, two jump drives and I'm covered!
