Thinking of taking the plunge and updating to a Z5c from a Z3c. For those that have had it for awhile what are your thoughts after owning it for a long time? I'm going to be importing the UK version to the USA as the fingerprint scanner is a big deal for me. Thinking of ordering from Handtec over in the UK as another site (xperiablog) recommended them and one or two others if you're importing. Interested if anyone has experience importing using them too. If anyone has been using it on AT&T would be interested in knowing how the reception is, etc. Any and all thoughts are welcome from long term owners! Thanks!
