!! What computer should I buy for voice recognition and video editing?

Check out [CompRec|http://comprec.com/] for recommendations.

!! Is the Light Pick like the Light Snake?

No, but it’s a [cool product for musicians|http://www.soundtech.com/lightsnake/index.asp] doing digital recording.

!! Computer Backups on a Mac?

The Geeks recommend an external [USB|Universal Serial Bus|http://en.wikipedia.org/wiki/USB] storage device or [[NAS|Network Attached Storage]|http://en.wikipedia.org/wiki/Network_Attached_Storage] device.

!! DVD-R or DVD+R?

[DVD+R|http://en.wikipedia.org/wiki/DVD+R] is better for data and archival, but [DVD-R|http://en.wikipedia.org/wiki/DVD-R] is much more compatible with the DVD player you would hook up to a TV.

!! Get a laptop now with Vista on the horizon?

Go ahead and get one now, but make sure you are buying a laptop with a discrete graphics chipset, not an integrated graphics chipset.

I just tested a dual USB2 / Firewire drive on a MacBook. Using transfering a 6GB file using firewire averaged 29.5GB per second. Using the USB2 interface averaged 18.07GB/second. I’ve tried this before on my dual core G5 and got the same results. You just said there was no difference. What gives?

!!! Lyle responds:

Ahh, interesting, I hadn’t seen testing numbers and was basing my answers on specs.
USB 2.0 Hi-Speed mode is 480 megabits per second, while the signalling rate of FireWire 400 (IEEE 1394a) is 393.216 Mbit/s” – [source|http://en.wikipedia.org/wiki/USB]

So, by spec, USB2 seems potentially faster. But I would not be surprised to see FireWire performing faster depending on the implementation. I know, for example, that Apple has spend a lot of resources on FireWire.

*! Here are two more plusses for USB 2.0:

But a speed difference that you have seen is a significant difference. Perhaps it is the implementation of the drive that you have. I will have to give it a try with my Seagate USB2/FireWire.
