I used a Lumia 800 until like 8 months ago and I did not like it so much. I think its main problem is the store, the most useful apps came out late (or still need to be available) and with less functions only to be upgraded later when everybody else had already passed over.
Besides that Lumia is a good phone, I dropped mine no many times and it didn't get any scratch and only after almost two years it started showing some little problems
I don't know if something changed tho
I hope I helped you a bit
