For prosumer, I am thinking of the Panasonic FZ18 or the Fujifilm S100SF (as recommended). Any others? I once had the Canon S1IS, but din quite like it. Hopefully these two will feel different.
Actually I am not sure if I will pick up photography as a hobby in the future. I sure like taking photos, and looking at beautiful photos, but I am not sure whether I will bring out my 2-3 kg camera assemble every weekend to take photos. I am more of a holiday photographer, but i want quality photos, especially of nature, mountains and valleys. I am not the "lets get everybody in the centre of the frame and snap a photo with the scenery behind" kind I compose and think about my photo before opening the shutter.
If you don't think you want the weight and might not pick up photography now. Consider getting the cheapest compact for your trip. Its enough to get the shots you need. Since you compose your shots, any camera can do it for you. I bought my Nikon Coolpix L14 because its the cheapest and its real light, fits in my pocket and my little 3 yr old girl can take fantastic photos with it. Visit my website to check out the photos if you don't believe me. Of course, I still prefer my D50 for its flexibility and I don't mind the weight.
Once you decide to take up photography, then get the DSLR, as technology changes so quickly, its no point buying until you really need it.
