Do not install IOS9 on your iPad 2!!!

So, Apple released IOS9 with a bunch of PR hoopla about how well it was optimised for older devices.

So, I installed it thinking, well my iPad 2 is running okay, and Apple promises the new version will not make it any worse, so what the hey, lets install IOS9.

What I forgot was that I never installed IOS8 because I heard it was a dog. Now I have IOS9, and my iPad has massive, massive lag!

The onscreen keyboard has a few seconds lag before the letters appear, scrolling through the apps is glacially slow, the whole thing is sluggish- basically it is a terrible UX.

And would you believe it is impossible to downgrade any lower than IOS 8.4.

I can't believe that QA at Apple signed off on IOS9 for iPad 2 because the experience sucks.

If I was cynical, I might think this was a deliberate strategy to make perfectly usable devices useless and push people to upgrade.

So DO NOT UPGRADE TO IOS 9!

Upgrading the RAM in a 2006 MacBook Pro (Merom) - MacBookPro2,2

I just upgraded the RAM in a 2006 Macbook Pro with the Merom Chipset - the system identifier for this mac is MacBookPro2,2 ( About this Mac ->More Info->System Report).

The ram it comes with is DDR2 667 Mhz 5300 SO-DIMM - this ram is hard to come by these days and I heard conflicting reports about whether higher speed RAM would work. Apparently the later model Penryn chipsets machines would not downclock the RAM and fail to to boot.

Anyway, my local computer store had some Patriot 800Mhz RAM for much cheaper than the Mac spec RAM could be had on ebay, so I took a chance and bought some.

After a false start because I didn't seat the RAM properly, I can report that 800 Mhz RAM works on my MacBookPro2,2 just fine!
