I think you're right on the battery thing, I'm just used to a pretty boring Nokia which didn't do much and so didn't really use any battery.
Anyway I bought this in a rush without telling my gf and essentially spoiled my christmas suprise (she had bought me a PAYG iPhone, I know I know no Android on that but this is politics
), so I'm going to be selling the Acer and getting a cheaper Android device for my dev (one of the HVGA ones).
Listing is here if anyone wants to save a few coins over the standard price:
Acer Liquid A1 Android Phone- 2 Days Old- Sim-Free UK on eBay (end time 19-Dec-09 11:43:40 GMT)
(using bit.ly because phpBB is stripping the ampersand)
Obviously I have to sell it as used but I think you all know how many days this phone has actually been out! I can have it posted to you for Christmas
