I just brought home a new, very sexy Macbook (2GHz, 1GB RAM). I have a PowerMac G5 that I use as my desktop, but I can't run Parallels to use MS Visual Studio, so I bought this for that. I also needed a laptop for mobility anyway, so it was a good mix. 1) I have thounsands of messages in Mail within hundreds of folders that I get through several POP3 accounts for my business and school. I really don't want to switch to IMAP because of the large amount of data I have within my accounts. I guess I could use the leave on server for x number of days feature of POP3 and just assume that both systems will see the mail within a reasonable amount of time? I need both systems to get all messages, but I also don't like the idea of having to sort through all my unread email two times. hmmm.... thoughts? 2) I'm going to write a cron job that will rsync my documents to my file server where my desktop currently sees them, so that will be taken care of. Anyone have any script that pings a host to see if it's alive and returns a bool? The first thing my script will have to do is ping the file server to see if it's there, because it will only be visable when I'm home. 3) iTunes. Oh boy. I have nearly 10,000 songs in iTunes. They are all on my server and I run iTunes on my desktop. Is there a way to share the index so I can have all my music available to me when I'm at home? Any thoughts on how to select a subset of that to store locally and take with me? I'd like to be able to add new music on either systems and have it show up on the other, so it's not just a matter of sharing the repository -- the index must also be (if this is possiable). What else am I missing? What else does a laptop power user need? Any cool tools? Oh, and where is the blasted delete key (not backspace, delete). For example, if my cursor is at the front of "this" word and I want to delete the t I would just hit delete. Now I have to arrow key to the right and use backspace (which, oddly enough, is labeled delete). EDIT: What about Address Book and iCal? I'd like those synced too. Anybody know how to do that? Thanks!
