I'm not sure whether I posted here. If I did not then I'd post again. :P
I bought a Z1. Awesome device... BUT THE SPEAKERS ARE RUBBISH. Actually my back glass broke on the Z1 and I lost the flap. I'm going for a holidays so I'd like to use it's wateproof capabilites so the Z1 is now in the repair store.
I'd write up a short comparison
Screen - much better on the Z1
Multitasking - Z1 obviously
Overall speed on a clean rom - ACTUALLY NOT THAT MUCH OF A DIFFERENCE ON BASIC APPS!
Speakers - useless on the Z1 - golden on the Xperia Play - I was actually amazed by how good they are after I got back to the Xperia Play
Heat - Xperia Play is cooler
Weight and size - I prefer the size of the Z1 and it's screen real estate. Much heavier than a Z1.
but the biggest downside compared to the Z1 is the battery. That's what really hurts me now.
All those good memories of flashing when I was here on the XDA as a newbie came back to me as I got back to the Xperia Play. It's such a great device for doing this stuff.
TBH? Better SoC and battery on the Xperia Play and I'd stay with it. :P
