Apple's updated its Wi-Fi router and backup drive combo, Time Capsule, with a guest mode and simultaneous dual-band wireless. I was pretty surprised at how wireless performance has increased, too.
Before I start explaining little things like speed, it's important to understand that the main reason why Time Capsule is cool is that it's the most easy to use device lazy Mactards like myself can back up their machine to. To do so, you just run a OS X Leopard program called Time Machine, which finds your Time Capsule—or any locally connected hard drive—and uses it as a backup HDD. Every day, more or less, by wireless or wired network, Time Machine (the software) and Time Capsule (the Wi-Fi router with a HDD in it) will continue to log changes you've made to your data. The physical drive inside comes in 1TB or 500GB capacities, and is a server drive rated for continous 24/7 use for quite awhile. [UPDATE: Jason just reminded me that last year, some people found the drives in the old Time Capsule to be rated for as a network server drive, but also, for consumer machines. So it's not as robust as some drives you'd find in, say, a data center.] Last fall, the Time Capsule saved my butt when my laptop's drive died overnight. Miraculously, after dropping in a new HDD, the OS X install discs asked me if I wanted to restore from a previous Time Capsule/Machine backup, and ended up losing only 2 hours of data. Two hours!
Mobile Me's service keeps track of the Time Capsule's address and passes it onto your machines that are registered with the service. It shows up as a drive on your Finder's side bar. Handy! But testing showed that the drive did not always show up on remote machines, and there's no clear way to force the remote drive to mount.
Guest Mode: Guest mode is extremely simple, creating a different network SSID and security key (optional) on the 2.4GHz band, while keeping the other two access points for your personal use. It separates the network from all your private network's disks, computers, and shared resources by using a different subnet. Guest mode does not include things we'd like to see, like a way to throttle guest bandwidth. It's not an important or useful feature, unless you're making a habit of letting people you don't trust use your internet. Unlike the Mobile Me remote disk function, guest mode is not a feature available to the old Time Machine by software update.
As before, the Time Capsule also has a USB port which can be used to plug in a second disk or printer, which can be shared on the network. I did not test the USB port with a printer, but our previous tests showed this function to be buggy at times. Using Time Capsule with a secondary storage device is not a bad idea, because Time Machine backups cannot be size limited; they'll use whatever disk space you have available to store the incremental changes in case you want to restore a file's version from a specific date in history. Time Machine backup software can also bog down the network when doing a backup, saturating the airwaves. Other machines in the house can now use the second SSID in such a case, but we also recommend Time Machine Editor, a third-party program that allows you to schedule backups whenever you want them. I use it to schedule backups at 1am when I'm usually not working. (These are annoying shortcomings of Time Machine software, and so not something we can blame the Time Capsule hardware entirely for. Not entirely.)
As before, Time Capsule has one ethernet port for your internet connection, and three gigabit ethernet jacks. That's one too few, in my book.
The unit runs very quietly, and sometimes you can hear the disks spinning up or seeking data, but its quiet enough for the notoriously anti-cooling-fan Steve Jobs. The unit's top runs, according to my heat sensor gun, between 100 and 120 degrees. It's warm, so I wouldn't rest anything on it, which would exasperate the heat build up.
Time Capsule is $500 for a 1TB and $300 for 500GB of storage. That's not a ton of storage for high-end machines these days, and multiple machines will almost certainly require the 1TB setup if you want to keep a moderately detailed history of your computers' data changes. As you'd expect from Apple, that's more than the cost of a 1TB external drive and a nice Wi-Fi router. Unlike when Time Capsule's first-generation box was released, you have options now.
If you have an AirPort Extreme, you can plug in a USB disk to the port on it for Time Capsule backups. If you want a NAS that can do Time Machine backups but also act as an iTunes music server, this HP media box will do the trick (although won't act as a Wi-Fi router). Since the new Time Capsule gets a bit more speed and distance out of it radios, and gets the useless guest mode, a refurbished Time Capsule could be a smart budget buy if those things aren't on your "must have" list. If you're a PC user, there's no Windows equivalent of Time Machine back up software included, nor is there a way to use Time Capsule as a remote disk from across the internet, so this product is not for you.
Regardless of my caveats, I just prefer the Time Capsule to these options as it fits a lot of back up functionality and network performance in one box.
