Occasionally, WordTracker will surprise you with an insight into something interesting going on in the world. Here’s a WordTracker result I just found:

What this tells us is that “iPhone Complaints” is the second most popular search term which ordinary web searches use to find information about the Apple iPhone.

It looks as if there are plenty of unhappy iPhone customers on the Internet!

iPhone Complaints

Common iPhone complaints include:

• No support for custom ringtones
• Battery life shorter than promised
• Sound volume insufficient
• Lack of Flash support in the web browser
• Built-in GPS is not user accessible
• Built-in Bluetooth cannot be used for data transfer
• Built-in camera has no ability to be adjusted
• Lack of useful applications (SSH, SFTP, VNC, Remote Desktop)
• No games
• No voice dialing
• Keyboard is very difficult to use

A lot of Apple/AT&T customers have already returned their iPhones for more mature devices such as the RIM BlackBerry.

I had avoided purchasing a Roomba because I could not imagine that a vacuum that small could be powerful enough to be useful — especially as this is the home of two long-haired cats and one long-haired wife.

I have been very pleasantly surprised by the power of the Roomba. It hasn’t had any trouble with the hair. It’s also much easier to clean than our large vacuum.

I purchased the “Roomba Scheduler Vacuuming Robot with Intelli-Bin.” The scheduler allows the Roomba to start automatically while we are sleeping or away from the house. Intelli-Bin tells me when the Roomba’s dust bin needs to be emptied.

Surprisingly, I haven’t made much use of either feature. I’ve been starting the Roomba manually and I’ve been emptying the dust bin before I start it.

This may be a result of how amusing it is to watch the Roomba work. The Roomba has no proximity sensor. It detects walls and other obstructions by bumping into them. Watching the Roombas work is somewhat akin to watching the Three Stooges. Plus, the Roomba’s will occasionally get themselves stuck on an obstruction — usually a cable that I have left carelessly laying around.

I’ve recently purchased the upgraded brushes specifically for pet hair. They do not appear to be noticeably improved over the basic brushes. However, there really is nothing at all wrong with the basic brushes.

In summary, I highly recommend the Roomba but you will be well served by purchasing the base model for significantly less money.

For the very basics, the motherboard features an AMD Socket-939 to support an AMD Athlon 64, Athlon 64 FX, or Athlon 64 X2 processor.

Data integrity is provided by an on-board SATA RAID controller. The Silicon Image Sil3114 chip supports RAID 0, RAID 1, RAID 0+1, and RAID 5.

System reliability is further enhanced by the magnetically levitated fan which is present on the heatsink.

Also featured on the motherboard are dual gigabit Ethernet ports.

For graphics, this motherboard sports a plethora of excellent features, including a 16x PCI Express bus and support for dual nVidia SLI-ready video cards.

In the audio department, the Karajan Audio audio system provides theater like 7.1/8ch sound.

I bought the 1GB model, which contains four 250MB ATA drives. I configured them as a RAID 5 array, which gave me a total of 750MB of disk space.

I’ve downloaded replacement firmware for the device from the dedicated fans at Terastation.org. This firmware adds the ability to telnet to the device. Once you do that, you can access the embedded Linux upon which the device operates.

Theoretically, I could replace the 4 250GB disks with larger drives, but 750GB fits my storage needs — today.

The real downside to the device is performance. The unit is CPU bound and that limits the speed at which you can copy data to and from the device.

Performance of a NAS device will never quite equal performance of DASD. I chose to go with a NAS solution because I wanted RAID 5 and I wanted a central storage device which would not be reliant on any of our computers.

The best feature of this NAS solution is the price. This is an awesome price for a home of SMB NAS solution.

If you don’t need high-performance file copies, this device is highly recommended.
