My new Asvine V200 Titanium with a medium nib arrived yesterday. The vacuum filler is much smoother than any of my V126s, and on par with my TWSBI Vac 700R. I also picked up a 30 ml bottle of Diamine Earl Grey, but the number of fills I'll be able to get with this pen is limited by the section being too wide to fit in the mouth of the bottle. I need to get different ink? Oh no!
Calculator is a TI-nspire CX CAS, and was my first calculator with a built-in CAS.
I'm in IT and have no real need for them either, but they touch me right in the happy nerd center of my brain!
