After my previous very happy relationship with a Sony Ericsson C905 (with a camera so good there was little reason to walk out of the door with two devices) I felt secure in the knowledge that upgrading to the Xperia X10 would be a sound choice. How wrong I was.
I want to start with the good points however. Timescape is a fantastic feature in the way it pulls together and tiles social media streams along with calls, texts, photos and emails so elegantly. I've often noticed people peering over my shoulder on trains. It's a good looker and intuitive to use and amazingly quick internet and wifi connection speeds making surfing the web an absolute joy. Even having a little flashing green light when a text has come in is a lovely feature.
All these good points can't disguise or weigh up against the bad ones. I've had the phone just short of a year and it has been away three times accounting for 45 days being 'repaired'. Each time being different from the last, OS issues, battery life lasting hours and non ability to recharge being the main issues. I received a new phone on the third occasion and this too has started to malfunction.
Apart from the issues with reliability there are a lot of things I found very disappointing about the X10. Contrary to the brilliance of the C905, the X10 camera is awful to the point of unusable, no flash (only a 'photo light' that needs switching on) and very slow to focus and then eventually take a picture. Text entry via the touchscreen keyboard is awful, characters often don't register when typed (particularly the A and L keys) and often type entry hangs and sometimes even crashes the phone. The entry slider often sticks which is a big problem when trying to answer a call.
This phone could've been a real game changer but the opportunity seems to have been missed.
