I've always liked the idea of a larger phone, and I have a craving for the Lumia 1520 (which sadly is not on T-Mobile). My friend said to me over two years ago that my first smartphone, the LG Thrill 4G, was way too big for me with a 4.3 in screen. He had a Mytouch 4g, a 3.8 in screen. Now he is using a Note 3 and he loves it. I don't think you can say a phone is too big without using it for at least a week. Overall, I feel the experience of a larger phone is much better than those with approximately 4" screens. I love my 521, but I also use a Nexus 4, for two reasons. One, the 521 is way too small for me, especially when typing text messages. Two, although the 521 has Wi-Fi calling, the Nexus 4 (unofficially) has LTE and gets better reception in my house. Wi-Fi calling would be sufficient if it was possible to send or receive multimedia messages. I don't think I could ever get another phone that has a screen smaller than 4 inches. All I'm waiting for is a new Lumia to come to T-Mobile and to have enough money to afford one. I personally think the Lumia 925 is overpriced on T-Mobile at 500 dollars, considering the 1520 is 550 off contract at the Microsoft Store, and the 925 is almost 100 dollars cheaper on AT&T.
