Searched the threads here and didn't find my questions directly addressed - so I thought I'd ask specifically... MacPro 1,1 (2x2.66)- still running Leopard 10.5.8; added a bunch of RAM and a couple of HD upgrades and that's all, really. Using it for all kinds of stuff - from wife's digital photo hobby (library 200K and counting...) some video editing, usual web surfing, some number crunching (stats programs and spreadsheets), garageband and protools for some home recording projects... On to the questions: I like having iCal and its ability for me to update on my phone while away, and have it sync with the desktop (and vice-versa) so we (wife and kids) can have our schedules all in one place, and freely update-able for all to see. With the whole MobileMe/iCloud/Mountain Lion issue, how will it be possible (or will it be possible) for me to keep this functionality with my current setup? Separate issue: Having no frame of reference, how useful would upgrading the video card be (still using the stock NVIDIA 7300) as I don't really do a lot of gaming - just some family video editing from time to time. Thanks for your input; sorry if this has been addressed - I did slog through some of the MacPro 1.1 vs ML threads but none really answered this. - c PS Already on the lookout for a used 4,1 as I think this is probably where I'm eventually headed.
