Oh i absolutely agree that the 7373 is a FAR FAR superior machine, but it does not have replaceable ram, which is something that the OP wants, hence suggested the 5000.
The 7373 is a very nice machine, but it does NOT have user replaceable RAM, nor does the XPS.
Check out the inspiron 5000 series. It does replaceable RAM, but its not as nice as the 7373.
If you have a budget of 90k, i would honestly and sincerely request that take a long hard look at FreeNAS.
If you need help, you can msg me on whatsapp or call me, as that would be much easier to explain :)
The OP6 is an amazing phone. Super fast and responsive.
If you can wait and spend the 50+k the Pixel 3 will cost then you should wait. If you want / need a new phone now, get the OP6 hands down.
