Query: Not p to the standards one would expect from Apple's OSx

I pre-ordered Leopard and received it on its release day. It does have some bugs.It does not recognize my music keyboard, it does not let me edit contacts in my address book, and for sure it has other bugs I did not yet discover.I'm a "converted" guy, so I am totally in love with my MacBook Pro but I must say that overall I'm disappointed in this Mac OSx.I had to buy a USB enclosure ($29.99), put a hard drive in it (I already had it), and re-install the Tiger 0.4.10 OSx (the previous version) to have it recognize my music keyboard and eventually edit my contacts.To those considering buying it I say "wait until the 11.0 version is released, by then most of the bugs should be resolved.
