Since you explicitly ask for analyzed and annotated data you might want to check out [?]The Gene Expression Atlas[?]. Which is:
"a semantically enriched database of meta-analysis based summary statistics over a curated subset of ArrayExpress Archive, servicing queries for condition-specific gene expression patterns as well as broader exploratory searches for biologically interesting genes/samples."
So technically it is a subset of ArrayExpress but the semantic enrichment and the standardized statistics might make it useful for your purpose.
I was about to also advice the old Stanford Micorarray Database. But the site at http://smd.stanford.edu appears to dead. Does anyone know what happened to that? It was in fact the oldest public microarray database and did contain quite some data that did not appear in GEO or ArrayExpress especially on yeast. Update: I checked. The Google cached date is July 1, so it is probably just down.
