I was using the ZTE for a month as my main phone. I got the T-Mobile $30/month Walmart plan and kept my iPhone 4 with me. Text input was okay as long as I pressed the buttons a little slower than what I'm used to on an iPhone 4. I think spell check was not yet available - or I didn't notice to turn it on so I had to spell perfectly. The map app would give me incorrect data (store/restaurant locations for Tucson Arizona) and it became annoying enough that I just relied on my iPhone for map stuff. In some rare occasions I couldn't get the phone to dial a number and that required a hard reset. Sometimes I couldn't get it to answer a call. I would press the button to answer but the phone wouldn't respond. I don't know if that's the OS problem or the ZTE not responding correctly to input. When viewing a missed call I would see the phone number appear first and then the name of the contact replace the number. As if it takes a fraction of a second for it to match the number to the name. It did that every time and I didn't add that many contacts to my phone. FYI I haven't updated to the most recent Firefox OS release so some of those issues might have been fixed.
