Well, I had a chance to get my head sorted and I finally finished the “b” version of the LT6502

Here you can see it next to the first version, I changed my mind about the case and went for translucent orange, it’s way more vivid in real life. I really do like the translucent material, it’s really different 🙂

The first big thing that’s different, it’s half the thickness of the old one;

It also has a larger, higher resolution screen. The screen is 1024×600 and is 10.1″, the previous one was 800×480 and 9″.
\nIt has a similar battery capacity, so should last about the same amount of time.

The screen also has a better contrast ratio being IPS rather than regular LCD, and the higher resolution really does show.

Here is a good example of that, and also the extra rows of text you can fit on the screen!

There are, of course, somethings I’d change
