Yahoo! Go? Yahoo! No! (from the Reg)
This
post by Andrew Orlowski is largely on target. I also found Yahoo! Go to be a massive memory suck that didn't do much that I couldn't already do with other services and utilities (push email - using the built in 6681 client and Seven Always on mail -check; Yahoo! news and info - using my wap browser - check; synchronization of my snaps with my desktop using Nokia PC suite - check). I liked the Yahoo! messenger software as well, but this can be done about as good as with IM Plus that also does other IM services as well. I do think that v2 of Yahoo! Go could be better if they listened to users and made it less intrusive regarding alerts and slimmed down the memory usage so it doesn't interfere with other apps.
(And by the way, email push on a more frequent basis would make that function more useful.)
