Weaknesses outweigh unfortunately

I own the HTC Tattoo now nearly 10 months in O2 contract.
It has already been enumerated much what the tattoo does everything well. I can connect me. Android is great that social networks integration truly succeeded HTC Sense a real asset.
Nevertheless, I have to annoy me every day about the tattoo actually. The biggest criticisms are:
1) The battery life! Having a laugh. Mostly I have to load the phone twice a day! In normal use (ie UMTS active, few phone calls, read news, little Facebook). This is certainly the main problem. That alone disqualifies the tattoo for normal use.
2.) display resolution. The small and Android untypical resolution are very, very much Apps by Android Markets simply not available.
3.) The camera is unusable. I'm not a bad photographer and had certainly no great claim to a Handycam but this is too bad. It is not possible to shoot a clear image even in an ideal light. I have also two different. Barcode scanner tried Apps and it never once managed to photograph a barcode so sharp that you could decode the barcode. Scrap!
4) performance. Ok, that is a bit on the Android architecture, but without an automatic task killer can be the Android after a short time barely use because it is too slow.

Conclusion: I would never buy it again. Unfortunately, my contract runs for one year - possibly I'll replace it anyway because the previously Alttagstauglichkeit is real limited.
