Less-approximate and more-approximate forms of loan words

Question

When Japanese incorporates a Western word, especially English, often the spelling rather than the pronunciation is respected in the transcription, thus, ending up with a transcription that is not the closest possible within the limitation of Japanese phonology. And then, later on, on some occasions, (often young) people start to use a form that is closer to the original pronunciation, and there arise two forms. What examples can you think of for such cases?

Examples

• Michael

  マイケル (traditional)
  マイコー(recent slang, especially referring to Michael Jackson)

• Volley ball

  バレーボール (traditional)
  バリボー (recent slang)

• People

  ピープル (traditional)
  ピーポー (recent slang, as in 一般ピーポー)

• Apple

  アップル (traditional)
  アポー (recent slang, especially referring to Apple computer Inc.)

The following are examples of different forms both respecting the original pronunciation, and are not examples of what I am asking:

• Benjamin

  ベンジャミン (as with the American president)
  ベンヤミン (as with the German philosopher)

Answer 1

Actually, there are also examples of a different, almost opposite phenomenon. For example, ドル, which looks like it represents the sound as heard, and the modern form オイルダラー based on American English pronunciation. I'm also reminded of the story I heard once that the word カメヤ (I think) was current during the Meiji period as a word for 'dog'. It was based on 'Come here!', which would now be カムヒヤー (yuk!). Also ズロース for 'drawers' (clothing), which is a wonderful rendition of the actual English pronunciation, much closer than ドロアーズ would be.

Answer 2

Here are some:

Key:

1 - Original spelling in katakana
2 - Newer spelling in katakana (tends to be closer to pronunciation)

1. アステリスク
2. アスタリスク 

Anything with ファ、フィ、フェ, etc. <--- Originally were not in Japanese (introduced in Meiji Era, but many elderly still use フア and フイ)

1. フアン
2. ファン

1. フアイル
2. ファイル

1. フイート
2. フィート

1. デズニ－ランド
2. ディズニーランド

1. キャンデー
2. キャンディ

Another more recent trend is adding the ッ to make it more close to the English pronunciation.

1. ドーナツ
2. ドーナッツ

Also the use of ヴィ instead of ビ (This example doesn't actually fit the pattern, both ビ and ヴィ have the same pronunciation, but since ビ and be also "bi", to make a distinction between "bi" and "v", ヴィ was introduced):

1. ビンテージ
2. ヴィンテージ

There are 2 versions of the word "smooth" in katakana, however according to the comment from @Matt there are historical references to スムーズ from 1918 which date before スムース, so it may not be applicable, if anyone has any evidence as to the etymology between the two words it would be appreciated:

1. スムース
2. スムーズ

Answer 3

Not sure if this one counts:

ボディー body, talking about wine etc
ナイスバディー nice body, talking about physical appearance. ナイスボディー also gets Google hits, though

Edit:

Remembered another:

パイナップル Dictionary version
パインアップル Not sure where this came from. Possibly thought to be truer to the English word pineapple in some sense.
パイナポー　Apparently there's a TV program called おはようパイナポー

Answer 4

Excuse me if I'm beside the point but, I think most people write and pronounce:
クレイジー, フェイク, フェイス, サブウェイ, メイク (イ over ー)
instead of
クレージー, フェーク, フェース, サブウェー, メーク

while they still write and pronounce:
ケーキ, セーフ, セーフティ, ステーキ, プレート (ー over イ)
rather than
ケイキ, セイフ, セイフティ, ステイキ/ステイク, プレイト.
Wonder what causes this difference...

And now we rather write:
コンピュータ, ナイスバディ, スパゲ(ッ)ティ, プリティ (with no ー at the end)
while we often pronounce them as
コンピューター, ナイスバディー, スパゲッティー, プリティー.

But we say and write:
カレンダー, フラワー, シェーバー, ヒーター, ドライヤー (with ー at the end)
rather than
カレンダ, フラワ, シェーバ, ヒータ, ドライヤ.

Hmm, why?
By the way, do you say/write プリンター or プリンタ?

Answer 5

I'm not sure how often some of these are used, but I think this might be one of them: "Tyrannosaurus".

• The most commonly used today: ティラノサウルス
• Others currently used: ティランノサウルス, タイラノサウルス, テュランノサウルス
• The classical forms: チラノサウルス, チランノサウルス
• Others which I found in Edict: ティラノザウルス, タイラノザウルス
