A palm computer and a subscription is all you need. Then you can register your tasting notes electronically. In addition, cooperating wine merchants (or other tasting organisers) can supply an electronic list of the wines to taste to make the data entry even easier. After that you just tap in your tasting notes with the palm computer stylus (or keyboard?) according to a predefined format. When you get back home you just synchronise it with your home (or office) computer. More info: TastingBuddy.com
