Questions & Answers about El técnico revisa mi tableta nueva.
Why translate revisa as "is checking" instead of using está revisando?
In Spanish, the simple present (revisa) is often used to describe actions happening right now, whereas English relies on the present continuous ("is checking"). While you absolutely could say está revisando to emphasize that he is in the very middle of doing it, the simple present is just as natural and much more common in Spanish for ongoing actions than it is in English.
Could I say mi nueva tableta instead of mi tableta nueva?
I usually hear people say la tablet in Latin America. Is tableta actually used?
Yes, though it depends on the context. While la tablet (borrowed from English) is extremely common in everyday Latin American speech, tableta is the formally correct Spanish term. You will frequently see tableta in writing, instruction manuals, or formal customer service settings like this one.
Could I use the verb chequear here instead of revisar?
