I recently acquired an HP laptop with Windows 8. It's pretty fast, yet I'm unsure if it was worth it (I got it because a Macbook of similar characteristics cost 3 times more), but basically because I was using (and still) an iMac for about 4 years and I kind of get used too much to many of their friendlier quirks. Typography related, I miss from Windows:
—The Mac keyboard allows to type additional characters besides the default layout much easier (the ones from the legacy Apple character encoding), which for me at least is very useful. I haven't found a good way to make the same on Windows 8 yet.
—Windows "Character map" is pretty dull looking comparer to the Mac equivalent and, unlike Mac, it hasn't been updated from years! (even if additional Unicode characters are still being added to their fonts).
—It don't have any fancy app to manage the fonts, although unlike Mac, I like they keep all in the same folder.
Any suggestions? It was worth it? Besides typography, I also work with Photoshop, InDesign, Illustrator and Premiere. All of the stuff is cross-plataform, but I'm starting to worry that were I work most people use Mac exclusive Final Cut for video edition.
