So I bought the new http://www.google.com/phone, the Nexus One at 365.21GBP. Deep breath.
I'm still on the last couple of months of my T-mobile G1's 18 month contract. Nonetheless, I've sent my G1 to my sister in Germany and hopefully she will get some use out of it.
I plan to end my contract with T-mobile and go on some PAYG plan, hopefully
with
Vodafone.
I bet you ending my T-mobile contract and porting my number will be an ordeal.

Talk about ordeals... the device took 16days to arrive, because Google's
fulfillment house in Indiana accidentally routed the N1 to Hong Kong. Google's
"Android support" customer services is absolutely abysmal. I contacted them
three times via Google checkout to tell them they have screwed up the package
routing. I basically only got through to them via an old University friend who
now works at Google. Shame. 
So the Nexus One(N1)! What do I think about it? It feels like a great upgrade
over the G1. The 1Ghz Snapdragon
amazed me awhile back on the Toshiba
TG01, so at last I have it!
However the battery performance seems on par with the G1. Sigh.
Despite a looming Nexus One update I though I'd rather be in control and hence I unlocked my Nexus One and "voided my warranty". I think it's a bit poor that I've voided my warrany because I want different software on it. I don't "void the warranty" if I put Linux on my Thinkpad, now do I?
Cyanogen's beta4 N1 mod is pretty wild. The USB
tethering feature is a must for me and it works far better than
Android 3G wifi tethering. Just turn it on, and ifconfig -a shows
usb0. dhclient usb0 and you're surfing on 3G. Why do operators make it so
hard?!
Since I'm into HTML5, I'm greatly enjoying using http://gmail.com and Calendar in the browser. It works amazingly well. I'm going to try avoid using the native Gmail client, though the native's 4 day background syncs are hard to beat.
I'm a little worried about the quality of the 3G
connection. The 3G scare
stories don't
help, though tbh I think the connection is the same as the G1. It's just that
since the phone is so much faster, the failings of UK mobile connectivity are
even more clear to see. 
You can upgrade your phone, but can you upgrade your connectivity? Well since my phone is unlocked I'll have to do some mobile speed testing again.

I also heard Google is giving out N1s at developer meets. Ah great, they know how to satify paying customers.
UPDATE: I've been lumped with a 60GBP DHL bill for taxes. OMG.
