I just did a quick search on Google News – I did two separate keyword searches: iPad and iSlate. Google is returning ~300 news articles referring to iPad and posted within last 7 days. When searching for iSlate I got ~6100 results (all search parameters were equal for both keywords). It certainly seems that iSlate is winning for now…
