That Tom Tom site keyboard one looks really interesting, but the F11 and F12 are hidden on the F1, F2 keys, and the PgUp/Dn keys are also hidden on the arrown keys, all requiring the Fn key to use. PgUp/Dn are important for page navigation when the scroll wheel doesn't suit.
It sounds like we are afflicted with the same gadet-itis

We like to try out this stuff, with the unfortunate side effect of accumulating an excess over time, and sometimes getting burned with bad designs

I keep going back to my trusty SK7500 IR board- it still has the best battery life, reliability and versatility of any RF/IR board I've tried.
However, for certain cases I'd like an RF board (range, non-line of sight, trackball and scroll wheel capabilities), so I bought the IO Gear 2.4Ghz with optical trackball and scroll wheel months ago-

I like optical trackballs, and wanted a real mouse scroll wheel. Also great price on the IO Gear, and respected brand.
Build quality is generally good, but the side rubber "bumper" trim adhesive let go recently due to simple heat from my hands over time. No big deal, but bad design choice. Also, battery life appears short vs the SK7500, though I beleive it's the batteries that were in the box but I'll have to double check.
This IO Gear appears functionally equivalent to the Adesso optical/scroll wheel RF board-

but costs less. I'd like to try the Adesso now that I 've held it in my hands at a local retailer- better ergonomics/grip and no trim to fall off
