The closest modern equivalent is the Keymouse Track and it's awesome. Source: 12 months ago

A somewhat more obscure, and fairly spendy option, is the KeyMouse. Each half has an optical sensor built into the bottom, and they also have trackball versions. Source: about 1 year ago

Well, there's the Keymouse which is a split keyboard with a mouse sensor under each half. That had quite a long development period - IIRC it was going to have smaller keys with Cherry ML low-profile switches so it wasn't too huge, and lots of people in here complained and asked for MX regardless of size.

I can't access anymore the pushbullet.com from my computer. I tried with chrome, firefox. Source: almost 1 year ago

Ah I see. Opening a tab isn't a problem, it's just that it opens pushbullet.com instead of https://www.pushbullet.com/#devices to see the text directly. I came up with a workaround with the "Redirector" extension that replaces the url. Source: about 1 year ago

Same issue. I have uninstalled (Revo) and installed 5 times and still can't get Pushbullet to work. Now it seems I have to got to pushbullet.com to read and send SMS, instead of doing it local on my PC with Windows 10. Seems to have happened in last 2 days. I can use it via internet access, but what happened to local functionality??? Source: about 1 year ago

I go to the pushbullet.com web site and they are all there as they should be. Source: over 1 year ago

Further when I go to pushbullet.com it doesn't show my recent devices. Although it does show it to me over the pushbullet icon in the toolbar. There are large gaps in my push history on pushbullet.com. Source: about 2 years ago
