On top of the performance issues, we were also disappointed with a few kinks that are present in the i-Buddie XP. Although the fan in the AC adapter may not seem like a big deal, it did get quite bothersome quite quickly. Also problematic was the heat that the i-Buddie XP with its 2100+ processor produced. The CPU was never bothered by the temperature of the system (meaning that the cooling solution works well) but our laps were (meaning that perhaps the cooling solution works too well). Obviously going with a slower Athlon XP processor or a Duron would decrease the heat produced by the system.
