Sony Ericsson Xperia X1 is not a bad phone, even with WinMo as the OS, but the price tag and features shoot the Xperia X1 in it’s own foot a bit.
Overall, the custom software upgrades Sony Ericsson added to WinMo 6.1 are good, but feel tacked on; this ranges from random 6.1 elements popping up over the custom UI when you get a call or text, text messages and missed calls that go unreported or the frozen screens that occur when you try to transition to another panel/app. It feels like Sony Ericsson chose WinMo by default, not because it’s the mobile OS they really wanted.
To be blunt, the Xperia X1 isn’t quite up to snuff with the top smartphones in the market from an overall standpoint. Whether you’re talking about its $800 price tag, stylus-based resistive touchscreen or 3.2 MP camera, this is a phone that would have fared better amongst early adopters a year or two ago. So that’s why nobody say the Xperia X1 is a bad phone—on the contrary.
