Summary: PROS: large screen, high resolution, zooming and annotation features. CONS: weight. ** ICARUS is rebranded from Onyx M92. The M92 review: the toolbar can be configured with 'Zooming Icons' which allows one tap access to 4 main functions (1.whole page, 2.full width, 3.full height, 4.rectangle select). Icon 1 and 4 are used frequently in landscape mode. Pressing the dedicated menu button gives plenty more rendering options. Text re-flow is possible.
Summary: I haven't had this Icarus Excel ereader for long enough to really put it through its paces, but so far I like it a lot. I got it primarily for reading--and taking handwritten notes on--pdf files, and it works well. Navigation could be a little easier and it would be really nice to be able to jump between several open documents, but it seems to serve its main purpose well.
