The HTC One A9 is readily available for pre-order at Unlocked Mobiles and Vodafone in the UK. The former store has the new smartphone listed for £450 (including VAT) for the grey and silver variants, while Vodafone will ask for £35 a month (with a £9 up front fee) for 1GB, or £45 if you'd like more data and entertainment.

The One A9 features a 5-inch 1080p display along with Qualcomm's Snapdragon 617 processor, 2GB of RAM and 16GB of on-board storage. The A9 is the first non-Nexus handset to launch with Android 6.0 Marshmallow. But should you pay £450 for this smartphone? Our Alex Dobie threw up a superb piece on reasons as to why you should avoid paying so much for the A9.
