Disadvantages of WAP
Well seeing as Jas mentioned the advantages I thought it would be a good idea to mention the disadvantages. Looking at WAP currently, there are a lot of formats and that Nokia phones and Sony Erricson use a different method of mark-up language. It also requires the WAP Gateway and WAP designers to contruct a site and at present they are not really widely available. There are other issues like bandwidth, but seeing as the wap sites are soo small this is not a major problem.
