You're not a fan of external drives but you have a lot of photos, documents, video and audio.....
yep. Permanent storage is on DVD. I have about 20 DVD-R's currently, and about 10 cd's. I have a large hard-drive on my desk top (250 gig) and my Dell XPS has a 110 gig hard-drive (still a way to small for my needs). My problem with external drives, is I take my laptop to church on Saturdays to work on the worship media. The area in the sound booth is small (big enough for the screen and keyboard - for the computer that is there). Sometimes I have to put my laptop on a chair next to me to use software I have, that they don't. Having to use an external drive would make it harder when needing to rip video or photos from one of their CD's/DVD's to my laptop for editing.
I do most of my editing for the church at home, but there are always those last minute changes.
I had an external hard drive once for my older desktop. The problem is another device taking up desk space. I have a small desk in a small room, so space is minimal (then you got the issue of more wires).
The only use I found with an external drive, was a case enclosure, when I had to pop-out a hard drive and place it in an enclosure to rescue the data on someone's dead desktop or laptop (with Window's PC's you would be surprized how many times a critical OS file get missing and you can't boot it up - or in the case of a friend of mine, his laptop was burned beyond recognition in a house fire - the hard drive was the only part that did not get damaged).
The other reason I am not a fan of external drives (especially DVD/CD) is all the under-write errors. Maybe they are better than they used to be, but we had a lot of problems with them at work. the data would not transfer to the drive fast enough for the drive to write properly. Reading from the external drive was ok, though slower than a built in one.
The other problem with external drives.... They take up one of your USB ports. I have an HP desktop with 6 USB ports. They are all in use (2 printers, web cam, ipod, scanner, and of course HP's media Center infra-red for the remote takes up a USB). All the USB hub's I tried never really worked properly.
I also had an IBM laptop about 10 years ago with an external floppy. Took a special cable that I would not get replaced when one of the pins bent.
Just speaking from experience. But I know Steve will wow us. I was going to use my tax-refund last year to buy a macbook, but with all the speculation of what is coming out, wanting to wait for leopard, and not being impressed with Vista - I temporarily opted for a cheaper Dell running XP (only because I needed it for work, my pentium III celeron I had for 5 years would not run the software I needed).
Right now I am glad I waited, because of the updates to iwork, ilife, and the initial problems with the macbook (plus they made small updates to make them almost as poweful as the macbook pro). This year I think I will get my mac.
