Well, this place has been very quiet!
Many of us have had our TMo Z1s' for several months now and I'm wondering how the device is working out for you?
Living in the Chicago area, my experience with the Z1s has been very positive. Getting great data speeds and performance from my Z1s. No lag, works the way I expected.
Since I travel quite a bit, the international roaming benefit of TMo's plan has been a GREAT benefit. Since I've I had my Z1s I have been to Switzerland twice and France once and the roaming performance has been very good. It's not as fast as in the States but totally acceptable. It's great to be able to respond to e-mails, texts and use Google maps while moving around without having to worry about additional charges.
The one main complaint I have with the Z1's is the output level on the headphone jack, it's a little on the low side....needs another 5 - 10db of output. Sound quality is great.
As to the screen, I have found it to be really pretty good. I think I like Sony's approach to accurate versus "vibrant / overblown" displays.
Battery life for the way I use my Z1s has been outstanding.
As to Sony and TMo support for the phone, I've been satisfied. Sure, I would like to get KitKat, but 4.3 seems to be working fine for me. I also like the Sony freebies offered through the Xperia Lounge. If you haven't checked them out, I would recommend it. Some great extra themes, free games and I just got the new Michael Jackson album for free. All very cool.
So, what's your experience? What would you change? Also, have you found any Z1s features that surprised you or that you find useful?
