To transliterate or not to transliterate?

[fox-c.livejournal.com]

At one point I think someone taught me that when writing in Russian, if there are certain words (like brand names or acronyms) in English that don't exist in Russian, we shouldn't transliterate them into Cyrillic.

For example, if I were talking about how to do something in PhotoShop I would leave the word PhotoShop in English characters(i.e. How do you do that in PhotoShop? Kак ето cделано на PhotoShop?). Is this wrong? Is it better or more correct to transliterate instead (Фотошоп)?

Question about accents in Russian...

[kasak.livejournal.com]

This is directed at native speakers of Russian.

What are some common charactaristics (stereotypes?) that tell you that someone is from a specific region/different country? For example, is there a specific accent to people who are native Ukrainian speakers? Kazakh speakers? Armenian speakers? etc...

Any input would be most helpful (and interesting?)

Как Вы знаете, что кое-то говорящий человек не носитель русского языка? Есть детали, которые выделятся о том, как говорит украинец? Казах? Армянин? итд...

Я буду признателен за ответы и информацию.
