On my new laptop, there are no buttons below the trackpad like I'm used to. Instead, you click on the bottom of the trackpad itself. However, the placement of the left click is way further to the left than one would expect. This has caused me to accidentally right click many times. Also, I occasionally click on a button when I meant to just scroll over it.
I've raised by accident when I meant to fold. Sometimes this works to my benefit as a
bluff, other times not so much. I also once folded pocket Aces in a Jackpot tourney when my opponent went all-in preflop when I meant to go all-in. Ironically, I bought this new laptop specifically for poker, but when I use a different laptop at work all day, I'll never get used to this different button placement and trackpad.
