Good for Windows, I guess. But I can't imagine anyone running this on Linux for real use. vim is just too powerful.
At a previous company, a pure Windows shop, people were having problems troubleshooting a customer's issue with import files on our 'data warehouse' application. They were csv files with about 20 columns and 1MM rows. Excel was barfing on it. Nobody could even open the csv because they were trying to use Excel.
I downloaded and installed cygwin and opened up the file in vim. They were amazed. In order to get the file to work for the test, I had to substitute "COMPANY" to a unique value so it would load. :1,$ s/COMPANY/COMPANY-001/g. Done.
They thought I was a wizard. Then they needed another change. 5 minutes and another file.
Then we needed dup entries in the file. Easy peasy to copy/paste 1000 rows in vim. Then we needed a 5MM row file. cp/sed/cat and voila. From then on out, I was the large-file guy.
