Is a 49-inch super-ultrawide too big for a normal desk?

It is about as wide as two 27-inch monitors, so plan on a desk at least 55 to 60 inches wide. A monitor arm helps because the included stand takes up depth.

Is 144 Hz worth it on a screen this size?

Yes for gaming and for smoother scrolling and window dragging. You need a DisplayPort or HDMI connection that supports the refresh rate, and a GPU that can drive the resolution.

How does IPS compare with VA at this size?

IPS gives better viewing angles and more consistent color across the curve. VA rivals usually offer deeper blacks and higher contrast, which matters more in a dark room.

Can I use it with a laptop?

Yes, over HDMI, but check that your laptop outputs the full resolution and refresh rate. Many laptops cap ultrawide output at lower refresh rates.

Does it work for a dual-PC or console setup?

It has limited inputs, so switching between a PC and a console means swapping cables or using a switch. Picture-by-picture modes vary, so confirm support before relying on it.
