I’ve been an Apple user for 12 years; I don’t get into justification arguments, nor do I diss Windows users, each to their own with their own requirements and their own cash.
I wouldn’t personally look for a deal on an older model; rather, I’d order a new MacBook Air with the M2 Chip, upgrade the RAM to 16GB, the storage to 1TB, which would give you an amazing machine. Not cheap @ 64,900 Baht, but will have good residual value even in 5 years time. Your shout of course, just my tuppence worth …. cheers
