Actually it's day 2 now - I've had the thing since lunchtime Friday.

First impressions

• not nearly as ugly in the flesh (in black) as the pictures
• keyboard is still a typing-with-thumbs device, but livable (and better than the m600 was by far)
• importing the numbers from my old phone was painful - there's no vcard support
• battery life is pants - but note, this is using the out of the box firmware. Some grovelling around the xda-dev forums and similar places gave me the tools I need to get. RC8 (current UK version, equivalent to US RC30) without giving up the root access accidentally left in the earlier one, so I hope it will now last all day on one charge
• camera's a bit rubbish

That was a list of criticisms, so I should add that on balance I actually love it so far, and it certainly blows the m600 out of the water. 100 quid for the handset, 20/month contract, which I reckon is not bad for a pocket-sized computer which happens also to be able to make phone calls
