Android phones, apps and tablets

No IP rating? (it's really nice not to worry about sweat/rain if you're riding)
Fingerpring reader? (although I rarely use mine)
AC wireless? (depends what router you have though)
Battery is on the smaller side too.

Seems pretty good though.

No comment on the actual phone, operating system/bloatware but the timing of your purchase, 'Now', may charge you a premium.
Apple seem to follow a set path through the calendar; new models for '(back) to college', which runs into Thanksgiving, then Bl*ck Friday/weekend, that drifts into Xmas. Other mobile phone manufacturers often use the new Apple price bands to maintain the prices of their better/flagship models in the early Autumn, but eventually crack and offer discounts close to Xmas.
(I picked up this LG G4 just before Xmas 2015 for £200 from Vodafone).
But if you have seen the XA1 U at a price you like go for it.
