I might be able to make it, depending on where my housing search is that week (I may be frantically looking at apartments and/or moving in somewhere). But also to consider is that the Met, the Cloisters, the Museum of Natural History, Brooklyn Museum and Brooklyn Botanical Gardens both all pay-what-you-will and their cafes are very nice. I don't think it'd be possible to get actual laptops into any of these places, but for meet-ups, they'd be good.

If you were thinking of a laptop-friendly space, there are a bunch of cafes I can think of in Midtown with big communal spaces and free wifi.
