As far as eBook readers go, I'm currently using Tucan. It's not too bad, although I kinda do miss CoolReader from Android days.

Has anyone gotten any luck with networking the phone with the rest of the devices in the house? I've been looking half across the Web for an app that had SMB/Samba client functionality, and I only found one paid app (nothing for free). It's amazing that a Windows-powered phone will not connect to Windows-powered PCs.

Also, anybody have any luck getting LTE to work on the 640/640XL? Celcom XPAX user here, and it does not seem to work - either that, or I'm not in coverage area. But I would have thought Bangsar Baru was a prime location...

The one thing I noticed about Windows Phone is that even on old hardware, it's quite responsive. The 640XL LTE, for instance (the phone I'm using), is actually quite an old Snapdragon. But bootup is fast, unlocking is fast, calling is fast, using the various productivity apps is fast, even playing Lara Croft: Relic Run is (mostly) fast. Granted, Crash Bandicoot 2 & 3 are horrifyingly slow, but playable nonetheless.

On another note, has anyone successfully used a Bluetooth keyboard on WP8.1 Update 2 phones? Looking to buy the Microsoft's Universal Mobile Keyboard, except every reviewer so far has said it doesn't work with WP. But Update 2 is supposed to include support for Bluetooth HID...
