Well Leon, I had a new Milwaukee 6256-6, that I ended up putting on eBay. Obviously you haven't used their new design, that new ergonomics style does not go well with the small base considering the vibration.
I had test drove a coworkers Bosch 1587 AVS before buying the Milwaukee, but felt it my duty to buy Milwaukee since my sawzall,router, drill are the same. Should have stuck with that test drive, because that is what I bought while the Milwaukee was listed on eBay. No regrets for selling that tool.
You're making a bigger deal out of blade change than what it is, fact is most woodworkers spend more time cutting than changing blades. I'll take a smooth action precise tool anyday over the decision if I'm going to spend a few seconds more per day changing a blade. I change blades for cutting, not because they break, I use HSS blades and not those carbon steel from HD or Lowes. Probably been three years since I've actually broke a HSS blade.
Your perspective comparing blade changing of these two tools to Dial Up and DSL, is far fetched if you really spent any time with the Bosch.
