I live in Newcastle as well. Here's what I had to say in another post (ignore the part about her DH finding a job):
I love Newcastle. Love it. LOVE. I think it's the perfect size -- the city centre is lovely and has a good variety of shops/pubs/museums & theatres, etc. The markets are open daily and are a lot of fun to wander around. Neither my husband nor I drive yet, but we're perfectly content with the metro and bus systems. If you're looking for nice places to live, focus on Jesmond (though that can be really pricey), Gosforth, and the newer parts of Longbenton (which is technically in North Tyneside, so the house and council tax costs are a little bit lower). High Heaton is also nice. DH and I are in Gosforth now and have fallen in love with it. We'll be buying a house next summer would like to stay here or move up a bit to Longbenton.
The universities are both good. U of Newcastle has an excellent reputation for research and Northumbria really focuses on teaching and learning and was recently voted the best "new" university in the country.
I don't think your husband will have a problem finding a job as there's a LOT of work going on in the city and the surrounding areas. I do know that the council's ALMO (Your Homes Newcastle) is in the process of building new and repairing all of the existing council houses and estates and they're in constant need of highly-skilled builders, electricians, etc.
Overall, it's just a lovely city and I wouldn't considering moving away unless we had a very good reason!
