I have an iPad Air w/LTE that I bought at a screaming deal off of eBay a year ago ($320 for 32GB!), and I love it. I use T-Mobile's 200mb/month free plan, so I use it sparingly. I wanted to know what incentives the carriers have offered in the past for iPads, when they've offered them, and if it would make sense for me to wait until they offer a deal on the new iPad rather than me just buying one at launch. I don't want a monthly data plan necessarily - some months I travel for work and would love multiple gigs of data, while other times T-Mobile's 200mb suits me just fine. This was my first LTE iPad, because I usually can't justify the $130 premium. Any help?
