Translation: I bought a PC yesterday.

昨日パソコンを買いました

I guess not everyone is fortunate enough to find one in a pile of trash in an alley. ¯_(ツ)_/¯

Edit: Downvoted so soon! I guess not everyone gets the reference either. This is what I get for trying to be funny, for once.

[sod_off]

So what's the reference?

Is there any reason why there isn't a "wa" between yesterday and computer? In most other examples the time seems to have a particle after it.

[Ever2662]

More context: particles aren't mandatory for words that describe relative moments of time, such us 今日, 昨日, 朝, etc. If the sentence used e.g., a specific day, like 火曜日, it would need to have a particle (probably に, although you could also use は for a different emphasis) to be correct.

[Sa967St]

In this case, it's optional. It's more polite to add the particle but it's not incorrect if you exclude it.

[butsuri]

I don't think it's a matter of politeness. You'd use は a) if yesterday had been raised as a topic of conversation or b) if you wanted to emphasize the contrast between yesterday and other days.

'I bought a personal computer yesterday'... And I was marked wrong for 'yesterday I bought a personal computer'.

[NathanDale3]

Report it.

1/7/18 "Yesterday I bought a PC" was accepted

[Sofia701655]

What about laptop (instead of PC)? You would also refer to one as パソコン right?

[Sa967St]

"Laptop" should be accepted. Both desktop computers and laptops are considered to be パソコン.

[Oscarvarium]

I must say "pasokon" had me baffled, I guess it's a shortening of "personal computer"? Is that the commonly used term for a computer or laptop of any kind?

[Matthias1414]

Yes, it is.

[Red859243]

For once this is true for me. It's a beast, and I'm excited.
