I lost my first Pencil on the first day of getting it before I'd actually even had a chance to use it. I had to wait, what, two months? for another one. So I get this and a day of portage and an hour of writing later my tip's noticeably degraded, like it's actually got very, very small bits of plastic hanging off the tip like I'd taken a cheese grater to it. I plan to pop into a Store for a replacement but I'm assuming they're like gold dust right now. Anyone else had similar issues? I only ink in bursts, and I've used the same Thinkpad Wacom stylus for years, and similarly my VAIO Duo/Canvas and Surface N-trig pens haven't needed a tip change yet.
