Am I Insane?

I believe all of you are likely going to respond with a resounding yes. I currently have Verizon service with my Samsung Galaxy Nexus. It is trying to die and I have ordered myself a Nexus 4 that I'm planning to use on T-Mobile's $30 prepaid plan. The catch is that T-Mobile has terrible data service here. The voice network is fine, but data is still EDGE. I'm in contract with Verizon until October. I'm planning to change my voice line with Verizon to a mobile broadband line and pickup a used Samsung SCH-LC11 from eBay to carry for when I need faster data on my phone, Chromebook, etc. So back to my original question. Am I insane?
