iDrive E2 is $40 a year for 1TB S3 compatible storage and they have promotions quite often. As always with cheap storage don’t rely on it and have a local NAS but it’s handy for offsite. I’ve just transferred out of Wasabi, who were cheap but are less so now.
Probably a Surface (if there’s one with a 5G modem) at the moment. I got a Lenovo Ideapad Duo Chromebook a few years ago but it’s become unusable now and hasn’t been jailbroken to my knowledge. There was a newer version but it wasn’t made available in the UK. Devices like the Juno look promising but are way too expensive for me (accepting they’re around the same price as an iPad and that Android devices are subsidised).
