I strongly agree here. Use plain English whenever possible and most items should be immediately apparent even to new users/programmers. Lowercase "t" and "v" are pointless when you consider that the SQL Server management tools instantly show what is what, not to mention the fact that if you are working on a database in any way you should already be aware of it's contents. Some exceptions have to be made to avoid reserved words, but this does not rise to level of needing to prefix everything.
