Earlier quoted context omitted.
Yeah the LightSail pricing doesn't look attractive at all. $40 if you need to get 2 cores - and dual core really should help with anything non-trivial.
All low-end VPS offerings use shared cores, so # of cores is a fairly useless comparison unless they also tell you the oversubscription rate or all of your neighbors are idle.
