Thank you Arek and SDS for your opinions,
as far as english words and .pl extension mix is concerned, i guess the value depends on the context, but in general i don't think an english word and .pl means it is necessarily worth less than its polish equivalent, many times there is no equivalent especially with new terms being invented which usually come from the English language, and if there is an equivalent very often it is very longer and not as "nice". That is why many companies choose english .pl names one example is polish Wireless Phone provider
