I'm not sure if the usage of 'considering' below is correct (or is there a better word to replace it?) and therefore I need your help:
It was still great though—considering that the computer had not been operated and upgraded over the year.
And also, are there any phrases/words that have the same meaning as 'creep into (sth/sb)', or 'spring into (sth/sb)'?
The use of 'considering'is fine for me. For 'spring into', you could use other verbs with a simialr meaning like 'leap'.
