I want to highlight that apps like this one (or Grammarly) are very useful for those of us who don't speak English as a first language but use it every day. By the way, we are a lot!
I get that they tend to foster a very specific writing style that can be boring, but most comms are not about fun but about conveying a message. I would not write a novel following their advice, but they are useful to replace a few words or add a comma here and there.
Lenovo Thinkpad X1 has 13,3" and a full powered processor. If you want even bigger you can go with a T420 (14"), which is more similar to the X220 but with a media unit.
One relatively easy solution for your email accounts problem: buy a domain, set up Google Apps, create a user and make that email address catch-all.
Now you can have as many email addresses as you want without needing to create them one by one. And if you work it a little more you can even answer as any of them and apply filters.
I have similar problems, but they are worse. Add to the mix suffered by the author working and having friends in a couple of countries/languages and you get my scenario.
I tried with one twitter account per language and doing groups in facebook, but it was too time consuming. Now I mix both languages with care and some won't like it, but I can't go further.
