I've owned ipad 1-3 and really don't see any point in owning one at this point. It was nice for browsing and youtube, but iOS is completely crippled for productivity so I always ended up bring my laptop with me when traveling, thus defeating the whole purpose of getting an ipad. I don't see myself purchasing another model until Apple enables file management and includes a USB port, which will obviously never happen. I'm picking up a Surface 2 this weekend instead; with full MS Office, desktop class browser and a FILE MANAGER I can finally ditch the laptop.
I wish the Surface Prom 2 had built in LTE. I hear the RT is getting it later on, but not the Pro
