Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
Has anyone looked into Memopal? It's $50 for 150GB, so not unlimited like what else has been discussed. But, if your data fits within those constraints, a plus side to me is the ability to access the files from your smart phone or a web client without having to download a zipped version of the file. So, it can act kind of like an ftp drive, but not exactly.
