Chris is a grad student and is looking to replace his desktop with an iPad. Leo says it can be done, but he wouldn't. He likes to be able to open multiple windows for research while having a window for Word to write with. He wouldn't want to write a paper on an ipad since it's pretty much sandboxed.
Leo says it can be done and if you're going to , then Keynote and Pages are far better than Word and Powerpoint. And since he uses an iPad 2 currently, he's several generations behind. So upgrading to a new ipad is a good idea. And Apple is probably going to announce a new iPad next month.
But Leo says it's a bit of a stretch to say that Ipad can be a Laptop replacement. Leo says t hat the Windows Surface Pro 3 is a better option since you can use it as a laptop, a tablet, or both. And it's a real computer. So it comes down to the comfort level on how it can be used. And it's also a limited amount of space and if you have textbooks that are digital, that can take up a lot of space really fast.
There's also talk that the new iOS 8 version will have multi Windows capability. If that's true, then it's a large leap forward towards really replacing your laptop with a tablet. Speaking of replacing a laptop, a MacBook Air may be a better option.
