Hi guys, Well I've been holding off upgrading to Leopard until the general consensus was that Parallels was ready for prime time with the new OS. I'm starting to get that feeling, based on posts here and around the net. I'd like someone from the Parallels team to offer their recommendation at this point -- Parallels 5160/Win XP on Tiger 10.4.10 has been rock solid for me. Can I expect equal results with 5582/Win XP and 10.5.1? (This would be on a 1st gen 2.16GHz Macbook Pro w/2GB RAM). Thanks for your advice.
