Hi: When I had already decided that I'm going to buy the next generation iPad Air and later a Windows laptop, I have seen a Surface Pro 3 in a store, and doubts have appeared. I was thinking of acquiring both an iPad and a Windows laptop to give them these uses: iPad (Air 2) Cellular ============ -> Reading eBooks, epubs mainly (through iBooks and Kindle app). -> Reading big PDFs, scientific articles and documents with a lot of graphics and even scanned pages (~100 or 200 MB and hundreds of pages). Annotating them would be extremely interesting. -> Reading comics. -> Surfing the Web, reading e-mails, calendar and Twitter... -> Editing documents and presentations created in my Mac or in my future laptop (with Microsoft Word/Powerpoint or Pages/Keynote). -> Other common tablet activities, such as photos or videos. This would be a very little percentage of my use with the tablet. Windows laptop (it must use Windows because of job issues). ========== -> Writing documents in LaTeX. -> Writing documents in Word and presentations in PowerPoint. -> Launching simulations in MATLAB. -> Programming (in MATLAB, Python, C/C++, Java...) In addition, I must say that I own a iMac which would be my main computer when I am at home. Due to the mobility I need (at work I don't have wireless access), I guess I should use a USB modem to connect the Surface Pro 3. I'm not sure if this is a pain. So, what do you think? Should I buy a Surface Pro 3 or an iPad + Windows laptop? I can't decide because I've never owned one of them. Thank you!
