I've got a k700i (my upgrade came through about 3 days after they were released in the UK) and they are quite frankly the dogs bollocks. It could do with a bit more memory (you can fit about 1hr or so of decent-quality video into the 42Mb it has), and it doesn't have a seek faciility for video playback so you have to split 10min-plus files into smaller chunks when you encode them if you intend to watch them in more than one sitting, but those are really my only issues with it. It's all about being able to watch my practise session from the night before on the bus on my way to work in the morning. Splinter Cell on the k700i is great, too.
