I seriously may be buying one of these today, I need a ledger to add to my Hardware wallet collection regardless.
If I wouldn’t have one, I’d definitely wait for 28th May and buy limited edition one. Especially for collection.I prefer the ease of use of the Trezor interface a bit better.
For some reason, the Ledger Nano S has a buggy interface... Perhaps they have fixed their issues, or perhaps they are working on making their interface less clunky? I do like the idea of a special pizza edition... a great and respectfully marketed contribution.
