yes, going to do the same. Ordering a Trezor now
Before you do that, do you know your the private key of the your wallet that is stuck in ethereum mist wallet? because if you have it backed up might be possible to access your wallet without downloading the sync data at all. Just obtain the unencrypted private key from mist then copy paste it on mew to access it there or back up your keystore folder from etehreum mist and try to access it on mew.
Actually just did that, got control over my Ethers via mew and json keystone-file.
Moved my funds to an Exodus account where I had 1 ETH while testing the program. Going to keep all ETH there until the Trezor arrives
