I have only had mine for 5 months but I too love it. Even when I look at all the upcoming and newly released tablets, I find myself loving my 7" of pure joy more and more.
Mine is on a Sprint Data plan and though I dont need that feature much, I still find it useful enough not to cancel.
I constantly find myself telling others that if you want a great android tablet, and are willing go live without honeycomb, this is the best.
