How I love posts from users who claim they're IT professionals and who keep returning their 4200 units because for them the speed increase is important and link trustworthy sources claiming double-digit performance increase... it's just a pile of BS, you know
I think it's a "mine is bigger than yours" thing. If a 4500 equipped model would suddenly appear, i bet they would moan at the nearest BB and request yet another replacement, poor souls
For newcomers - no matter what cpu have you received - as long as your unit (the Surface!) is okay (no excessive bleeding, no faulty components), be happy with it and don't read threads like this one.
No I started this thread and it is totally different. I wasn't trying to break the news about the Surface Pro 2.5. Heck we already had a thread here about that. This thread and title was all about the 4300u Lot Numbers! So yes I think I started what has now become a PITA thread.
Just got my surface pro 2 today, asked for lot 1350 at best buy, luckily they had a few and now I have the 1.9gh and 4300u graphics card in it. Really happy with it so far and can't wait to keep playing around with it, having to charge it for the first time right now.
