No pricing on that sSDR yet, but their single channel M.2 SDR is $360. My guess it the dual channel one would be close to $500. Nice, but above my impulse buy threshold... (It won't surprise me if a Flipper One with that sSDR in it will cost close to $1,500.)
This is where I land as well, except I'd go higher. Ukraine has caused the pricing of any FPGA equipped SDR to skyrocket.
Plus incredibly high sample rates that the sSDR supports would likely result in a lot of drops in sampling due to sustained throughput issues of the device itself. You'd be surprised how much dropping occurs on even fairly modern/grunty machines. I used to record X band weather satellite baseband on a HP Dev One and ended up using a ramdisk for baseband recording as the PCIe 2.0 bus wasn't able to handle the sustained write speeds once the nvme drive's buffer was maxed out. Basically anything above 30Msps would go to RAM.
As strong as the lure is of a cute RF device, I've never bought a flipper as I couldn't justify it given the multitude of other SDRs and radio hardware I have. EG RFNM, BladeRF 2.0 xA4, hackRF clone, RTL-SDRs and NESDRs, as well as a YardStick.
Lots of laptops have M.2 ports. You can also get M.2 for Raspberry Pi. I don't know why I would buy this device. I guess it's cool that it's small, but the screen sucks.
