I'll be switching from the Thunderbolt. I actually really like the Thunderbolt (unlike a lot of other people, it seems), but I just like the Nexus (and ICS) sooooo much more. I'm a little sheepish about having to pay full retail for it (I just got my new two year agreement back in April, when I got the Thunderbolt), but eh...
What are the chances Verizon would sell it to me for a bit cheaper? I don't expect to get the regular upgrade price, but any amount off at all would be nice. What about employee discounts (not a Verizon employee, but how you can get discounts based on where you work)? I've heard you can apply your discounts to accessories, but could you do it for off-contract phones, too? That'd be nice.
