The new Sony Ericsson t610 looks good, it solves many of the problems I've found with the t68i. This was not a hands on review, but a summary of reviews I've read.
They have made ui faster and more flexible as well as increasing the size and number of colours of the screen. They have replaced the yes no keys with programmable soft keys, which should improve the experience a good deal. Amazingly the phone is now smaller, though marginally heavier though the camera is now internal, as the t68i camera was a clipon.
Estimated uk price will be around 99 with contract, so 130-150 with upgrade maybe. I'll definitely be upgrading my t68i come contract renewal.
It supports gaming and java, so might make a decent mobile blogging tool. It also has 4 channel sound with a mirrored finish aluminium body. It is iSync compatible too and has bluetooth, gprs etc.
Essentially all my criticisms of the t68 have been addressed and the phone is not too expensive either, I'm not sure I need the bulk and faff of a p800, phones should be small.
